INTRODUCTION: Sudden deafness is characterized by an abrupt onset, often idiopathic and tinnitus is present, and becomes the main complaint in up to 80% of patients. OBJECTIVE: To review carefully all studies of the past 10 years on sudden deafness and tinnitus and analyze the effectiveness of oral and intratympanic steroids for tinnitus control in eight patients with sudden deafness and severe disabling tinnitus. METHOD: An analytical prospective in which 64 patients after sudden deafness with tinnitus were monitored and 08 of these suffering with severe disabling tinnitus underwent hearing evaluation and application of the Tinnitus Handicap Inventory and Visual Analogue Scale before, during and after sudden deafness treated with oral and intratympanic steroids. Sudden sensorineural hearing loss (SSHL) was first described by De Kleyn in 1944 and defined as a hearing loss of at least 30 dB in three sequential frequencies in the standard pure-tone audiogram over 3 days or less1.
Population studies of SSHL show a wide distribution, ranging from 5 to 30 cases per 100.000 per year, with an average of 50-60 years and no sex preference.
Hypotheses are proposed to explain the pathogenesis of sudden hearing loss as the vascular, the viral, the autoimmune and the rupture of membranes one.
Patients with tinnitus and SSHL are very frustrated by residual tinnitus even after accomplishment of the treatment for SSHNL.
All patients received information about the risks and expectations of therapy and signed a free informed consent form.
Next, salvage therapy with intratympanic methyl-prednisolone was offered to XX patients with a diagnosis of SHL, after systemic therapy failed and no improvements were demonstrated audiometrically.
All patients underwent tonal and vocal audiometry and speech recognition rate analysis done by audiologists before and after treatment. Prior to any procedure, patients were oriented as to the risks and expectations about the procedure and signed a free informed consent form. After intratympanic application of the steroid, the patient remained in the supine position and cervical rotation at 45? for 30 minutes to maximize exposure of the round window membrane to the solution. The criteria for defining successful recovery after therapy vary in the literature on intratympanic therapy. All patients underwent Questionnaire Tinnitus Handicap Inventory (THI)5 and the Visual Analogue Scale (VAS) to assess quantitatively and qualitatively the therapeutic response in relation to tinnitus. The search strategy employed in the literature review was guided by the combination of two descriptors indexed in MeSH (Medical Subject Headings): sudden deafness and tinnitus.
Most of the patients had vertigo associated with sudden deafness, being classified as mild in 75% of cases and severe in 12.5%. We performed a literature search with the following aliases: sudden hearing loss and tinnitus.
Their ages ranged from 26-73 years with a mean of 39,5 years and the ear most affected was the left ear (n = 5). In this study, we chose to intratympanic corticosteroid associated with oral corticosteroids and showed that this association was particularly effective in relation to tinnitus, from the eight cases analyzed, seven of these showed a significant improvement verified by THI and EVA. Several factors may affect the prognosis of the PANSS (eg, hearing loss severity, symptoms duration before treatment, vertigo, type of audiogram, and the patients ages). Regarding hearing improvement, only two patients had good responses to therapeutic intervention. Given the results, we note that in addition to the proposed intervention, especially those cases where there were no improvement or even where there were worsening of symptoms over time, there are other recommended therapies such as cognitive-behavioral and Tinnitus Retraining Therapy. Some therapies for tinnitus tend to focus on the impact of noise on the quality of life and humor, and include antidepressants, anticonvulsants and benzodiazepines, or attempt to mask their own noise with white noise generators. In 2005, a review of published randomized clinical trials addressing the correlation between sudden sensorineural hearing loss and tinnitus and treatment by hyperbaric oxygen therapy (HBOT). The sudden sensorineural hearing loss (SSHL) is a considerable diagnostic challenge because it can be caused by many different diseases and there is still no definitive treatment for PANSS universally accepted. In search of a therapeutic approach, the efficacy of enoxaparin sodium associated with venous hemofiltration was studied. In 2008, Ishida et al.15 investigated how the symptoms of ear fullness, tinnitus and otoacoustic emissions (OAE) varied over the course of recovery thresholds in pure tone audiometry in SSHL.
Kleinjung et al.16, in 2009, described the case of a man of 55 years who suffered from tinnitus in the right ear as a result of a SSHL. Hikita-Watanabe et al.17, in 2010, in an article entitled "Tinnitus as a prognostic factor of sudden deafness", rebound that in the group "buzzing rare" there was a worst prognosis to hear than in the group "buzz often".
In 2012, Fioretti et al.18 described the case of a 67 years-old women with severe and disabling tinnitus in the right ear, hyperacusis and mild headache.
In 2012, a research was also conducted by Ramos et al.10, in which the authors assessed the effectiveness of cochlear implants in patients with SSHL and disabling tinnitus.
The tinnitus severity was assessed using the Tinnitus Handicap Inventory (THI) and the Visual Analogue Scale (VAS) before and after deployment. Given the results, it can be concluded that the reduction of tinnitus after cochlear implantation may be due to several mechanisms such as habituation, acoustic masking, direct stimulation of the cochlear nerve and reorganization of cortical areas. Michiba et al.19, in 2013, highlighted the fact that many patients are frustrated with the SSHL residual buzz, even after complete SSHL treatment.
The hearing improvement rate was determined by comparing the thresholds before and 6 months after initiation of treatment. The improvement of hearing thresholds were significantly correlated with improvement in the score of tinnitus 6 months after initiation of treatment compared with before treatment. Generally, subjective feelings for the ringing residual 6 months after initiation of SSHL treatment are almost the same as 24 months after treatment. Patients that carriers sudden deafness and severe disabling tinnitus, and underwent intratympanic and oral corticosteroids showed, in this study, significant reduction or remission of tinnitus. Paper submitted to the ITJ-SGP (Publishing Management System) on September 4, 2013; and accepted on October 4, 2013.
The aim of this study was to determine the effects of various treatment modalities employed for patients with sudden sensorineural hearing loss (SHL). Sudden sensorineural hearing loss (SHL) is defined as hearing loss equal to or greater than 30 dB at three or more consecutive frequencies, the onset of which takes place over a period of 3 days or fewer [1]. Treatment is controversial and can involve anti-inflammatory drugs (steroids), vasodilators, antiviral agents, plasma expanders, diuretics, calcium channel antagonists, hyperbaric chamber use, carbogen, anticoagulants and, more recently, intratympanic corticosteroids [6-11].
The aim of this study was to observe the progression of SHL in patients who underwent different treatments at the SHL outpatient facility of our institution and to describe clinical and epidemiological aspects. This retrospective study analyzed the records of patients treated in the sudden hearing loss section of the Otolaryngology Department, Clinic Hospital School of Medicine, University of Sao Paulo, Brazil, between 1996 and 2006. All patients underwent imaging tests (temporal bone magnetic resonance imaging or computed tomography) and complete blood cell counts. The patients underwent serial audiometric testing at baseline and after 30, 90, 120, and 180 days of treatment. Considering all the cases, we observed significant posttreatment reductions in low- and high-frequency PTA (Table 3).
Estimates have shown that among patients with SHL, the mean age ranges from 43 to 53 years, the gender distribution is equivalent, and the hearing loss is unilateral in more than 95% of cases [2,4,11,13,14], similar to what we observed in our study. Approximately 25-40% of patients with SHL present with concomitant upper-airway infection [11]. According to Rauch [11], vestibular symptoms were identified in 28-57% of cases, as compared with 32-40% reported by Nakashima et al. The most common etiological factors identified for SHL were those that are not the most frequent but can be directly identified through clinical history, blood samples, or imaging studies, including autoimmune diseases, acoustic trauma, ototoxic drugs, Lyme disease, and ear malformations. Theoretically, this anatomical presentation predisposes to hypoxia, spasms, thrombi, and hemorrhage, especially at the cochlear apex, primarily affecting the response to low frequencies [23]. When we analyzed the cases in which PTA normalized, we observed that in most cases baseline PTA was moderate and the etiology was unknown.
Among the five treatment groups, the differences in ΔPTA were not statistically significant at any frequency. For low-frequency and high-frequency PTA, we observed an inverse linear correlation between time from onset to treatment and audiometric response presented by the patients. On the basis of our analysis, we can infer that plasma expanders do not improve the efficacy of the corticosteroidacyclovir combination used in managing SHL in patients.
Sudden hearing loss - or sudden sensorineural hearing loss - is defined as a loss greater than 30dB in three contiguous frequencies, occurring over a period of less than three days. Sudden sensorineural hearing loss  (SSNHL) may be noticed upon awakening in the morning or develop rapidly over hours or days. Incidents of Sudden sensorineural hearing loss are mostly unilateral, only 2% experience a case of bilateral sudden sensorineural hearing loss. Treatment with systemic steroids has proven to be successful in many cases, but sudden sensorineural hearing loss should be treated as soon as possible.

People with Meniere's will have sudden dizzy spells after experiencing tinnitus or muffled hearing.
Although there is no exact cause of Meniere's, scientists believe that it has something to do with high pressure of the fluid in part of the inner ear. Meniere's disease varies dramatically from person to person, so individuals can experience an array of different symptoms that occur daily or just once a year. Symptoms usually begin with the feeling of pressure in the ear, followed by tinnitus, decreased hearing and vertigo. Early state: During this time, a person will experience sudden and often out-of-the-blue episodes of vertigo that last anywhere from 20 minutes to an entire day. Middle stage: Symptoms of vertigo tend to become less severe during this stage, while hearing loss and tinnitus will increase in severity.
In order to diagnose the disease, an individual must experience tinnitus, hearing loss and vertigo more than once. Since Meniere's disease is not curable, many treatment options involve patients changing their habits or diet, or taking medications.
Salt intake: Salt helps the body to retain water, so reduce intake of sodium-rich beverages and foods. Decrease caffeine: Caffeinated beverages can make symptoms like tinnitus worse, so it is best to decrease the amount of this stimulant in your diet. Monosodium glutamate (MSG): Although many food manufacturers have begun to avoid use of MSG because of its harmful properties, it is still important to check labels to make sure it is not added. Smaller meals: More experts are proving there are greater benefits to the body if you consume five to six smaller meals throughout the day instead of three larger meals. Diabetes mellitus, frequently called diabetes for short, is sorted into two categories – type 1 and type 2. Optimists see the glass half-full, pessimists see the glass half-empty and engineers see a glass that’s twice as big as it needs to be. In the United States, otitis media alone causes adults and children to visit physicians 25 million times per year, according to the American Academy of Otolaryngology – Head and Neck Surgery. The oldest medical specialty in the United States is otolaryngology, the study of the ears, nose and throat, according to the American Academy of Otolaryngology – Head and Neck Surgery. In old Western movies, the two most powerful cowboys in town must inevitably face off, and there can only be one winner at the end of the showdown.
Eight patients treated with intratympanic and oral corticosteroids were selected, just two patients showed improvement over the hearing but seven of them showed big improvement in their tinnitus, which was demonstrated by an improvement in the values of the degrees of severity of tinnitus.
In most cases, there is a unilateral hearing loss, with bilateral involvement reported en less than 5%1. However, the current trend is to consider the sudden deafness as a disease of multifactorial etiology2. In idiopathic cases, the oral corticosteroids are widely used, although the supporting evidence is weak.


However, there are few theories trying to explain its mechanism, one of than associates this symptom with a maladaptive attempts of a cortical reorganization process due to peripheral deafferentation4. The majority ask doctors about the prognosis of residual tinnitus at the final day of medical treatment for SSNHL.
From June 2011 to July 2013, 64 patients with a diagnosis of sudden sensorineural hearing loss were seen at the otorhinolaryngology outpatient and emergency unit of our Center, Eight was suffering from severe disabling tinnitus. A detailed clinical history was taken, followed by an otoneurological examination, and an initial audiological assessment by tonal and vocal audiometry, impedance testing, speech recognition rate (SRR), laboratory tests, and an image exam (magnetic resonance imaging with contrast of the inner auditory canal). Eight patients suffering from severe disabling tinnitus agreed to undergo rescue therapy and signed the free informed consent form to be included in this study. All patients with fluctuating hearing loss or suspected Meniere's disease were also excluded from this study.
A second injection was done if there was any possibility that the first injection was not adequate. A 20 dB improvement at 0.5, 1 and 2KHz, or a 20% improvement in discrimination was enough to consider the intervention as successful.
In the Visual Analogue Scale (VAS) score ranges from 1 to 10, where 10 represents the highest degree of tinnitus severity. However, corticosteroids seem to have universal acceptance and are the ones with proven effectiveness. Such treatments aim to improve inner ear oxygenation and include vasodilators, plasma expanders, steroids and anticoagulants11.
In the EVA, it is observed that 100% of patients had a score greater than or equal to 7 and a significant reduction in scores of patients 1, 2, 3, 4, 7 and 8, in order to reduce at least two points on score and the same was observed in the degree of severity in THI (Table 1). Patient 2, despite their age, presents a clinical STD (sexually transmitted disease) that could prevent or reduce the effectiveness of the proposed treatment.
The administration of hyperbaric oxygen is based on the argument that both the hearing loss and the tinnitus may result from a hypoxic event in the cochlea, and that hyperbaric oxygen therapy may be able to reverse the oxygen deficit. Eight patients were followed with improvement in SSHL auditory thresholds (Group A) and eight patients with poor hearing improvement (Group B), to elucidate the behavior of these symptoms in your ongoing recovery.
Several therapeutic efforts including intravenous steroids and graft in the round window showed no positive responses. All subjects had SSHL, although the group "short" had a better prognosis than the group "longer duration" when restricted to SSHL accompanied by tinnitus. Ten patients with sudden hearing loss and severe-profound unilateral tinnitus associates were implanted with a mean age of 42.7 years deployment.
It was conducted a prospective study that analyzed gender, laterality and age of patients, along with changes in the level of hearing and tinnitus, after scoring early SSHL to determine the prognostic factors of residual tinnitus after the last day of treatment for SSHL.
The tinnitus was assessed subjectively by a questionnaire before, 6 and 24 months after initiation of treatment.
The scores of tinnitus in all three items were significantly better 6 months after initiation of treatment comparing with the last treatment.
Especially younger patients with hearing improvement achieve an improvement of tinnitus in the period between 6 and 24 months after initiation of treatment.
Specialist in Otology and Neurotology by Harvard Medical School, Boston, MA, USA, PhD in Medical Sciences from the University of Brasilia, Professor at Health Sciences School - University of Brasilia - Brasilia - DF - Brazil. We retrospectively evaluated the records of patients treated in the sudden hearing loss section of the Otolaryngology Department at Clinic Hospital, School of Medicine, University of Sao Paulo, Brazil, between 1996 and 2006.
Approximately one-third of affected patients improve spontaneously, most within the first 2 weeks of disease progression [1,3].
The inclusion criterion was SHL of sudden onset over a 72-hour period, equal to or greater than 30 dB at three or more consecutive frequencies. Group II included patients who had a 0- to 15-day history of SHL and in whom the use of plasma expanders was contraindicated owing to systemic hypertension, cardiopathy, coagulation disorder, or renal failure. The laboratory exams included erythrocyte sedimentation rate, fasting glucose, cholesterol, triglycerides, free thyroxine and thyroid-stimulating hormone, circulating immunocomplex, complement, rheumatoid factor, and antinuclear factor. The only epidemiological study of SHL published to date was performed in Japan in three different years and different decades [13]. However, other authors [2] observed that, unlike our finding, only 11% of their SHL patients presented with concomitant upper-airway infection. The autoimmune diseases that can lead to SHL are autoimmune inner-ear disease and immunemediated systemic disease leading to a secondary innerear injury. One piece of evidence supporting this hypothesis is the fact that various authors have reported among patients with SHL seropositivity for a number of viruses, including herpes simplex, varicella zoster, cytomegalovirus, influenza, parainfluenza, rubella, and mumps [9, 18-20]. Studies involving patients with SHL have shown evidence of sudden-onset cochlear ischemia and an association between SHL and systemic vascular diseases [23]. In fact, vascular etiology is a very promising theory, but confirming and explaining it is difficult. Despite the lack of a control group, the findings of our study can be compared with those presented in the literature. Among the remaining cases, the most common etiology was diabetes mellitus, followed by viral causes.
The improvement in PTA was less pronounced in patients in groups IV and V (who started treatment at least 15 days after the onset of SHL) than in the other patients, although the difference was not statistically significant. This finding is in agreement with those of other studies showing that earlier initiation of treatment improves prognosis [1,4,25].
The chances of full hearing recovery are smaller for patients with severe loss of hearing and when the sudden sensorineural hearing loss is accompanied by vertigo. Studies have shown that those who have begun treatment within two to four weeks have the greatest chance of recovery. In 30-70% of cases with permanent hearing loss, sudden sensorineural hearing loss may be treated with various types of hearing aids or cochlear implants, as determined by your hearing health specialists. The only condition is that you provide a direct link to the specific article you use on the page where you quote us. This disease can cause pressure or pain in the ear, severe cases of dizziness or vertigo and a ringing or roaring noise, also known as tinnitus.
Symptoms vary from person to person, and some will experience many attacks over a period of several days, and others will have one attack every once in awhile. An individual's ear may feel blocked or full, and they may have some hearing loss, which typically goes away after the episode fades. However, tinnitus and hearing loss will likely get progressively worse, and people will likely experience unsteady balance regularly. Since the ailment affects an individual's hearing, one may lose confidence to have conversations with others or at work, which can contribute to depression or anxiety. Since all of these issues can stand alone or be associated with other diseases, Meniere's can sometimes be difficult to diagnose. Dietary changes can decrease the amount of fluid in the inner ear, which can weaken the symptoms of the disease.

Knowledge of drug absorption has led to modifications in the creation and administration of oral drugs. As seen in the joke, the stereotype for engineers is that they see problems and find solutions. When it comes to microencapsulation, there are two powerful approaches, but both are winners, as each has its advantages. In many cases, the etiology remains unknown and constitutes a major challenge, even after complete otologic evaluation, and these cases are classified as idiopathic sudden deafness3.
Intratympanic dexamethasone has been trialled in patients with sudden sensorineural hearing loss, because it provides a high concentration of steroids in the labyrinth in animal models1, although its evidence are conflicting. This study was approved by the institutional review board of the Medical School and the University Hospital in which it was carried out.
Below are the details of inclusion criteria, the audiometric assessment, application technique, analysis of The Tinnitus Handicap Inventory and Analogue Visual Scale for Tinnitus and outcome of recovery of Hearing Loss and Tinnitus. The speech recognition rate (SRR) was based on the percentage of correct answers for monosyllables.
EMLA cream was placed in the outer ear canal and the tympanic membrane and left for 30 to 45 minutes, after which it was removed.
Failure of oral prednisolone therapy was absence of improvement, as just described, after 14 days of treatment. In relation to the mean-tone, obtained as a result of the following classifications: mild (25%), moderate (25%), severe (25%) and deep (25%). Sudden hearing loss can occur mainly in the age group 43-53 years7, with equal gender distribution. Already Patient 4 also showed no change in auditory thresholds, showed a significant change in their tinnitus. Significant increase of 25% was found in the hearing threshold of patients undergoing this type of therapy, but in relation to tinnitus, the study was not conclusive13. Seven patients (70%) treated with enoxaparin sodium and venous hemofiltration (group A) had reduced subjective tinnitus and four patients (40%) showed a complete hearing recovery after the first procedure. Given the failure of the rapies performed, it was suggested the cochlear implant that, according to the authors, is a routine procedure for patients with profound bilateral sensorineural hearing loss, and succeeded, some reports showed a suppression of tinnitus as a side effect after implantation. This indicates that the tinnitus by itself cannot be a problem sign in the prognosis of hearing, but may be an essential sound for the early recovery of the damaged auditory system. Shortly after the standard fitting procedure, the patient reported a reduction of tinnitus, hyperacusis, and the headache disappeared completely in the follow-up of 3, 6 and 12 months. Seven patients experienced an improvement inTHI in different degrees and in only one patient there was no change.
44 patients with SSHL were followed, all treated with systemic steroids administration for 2 weeks and oral ingestion of vasoactive drugs and B12 vitamin for 6 months.
Among the comparison between 6 and 24 months after initiation of treatment, there was no significant change.

Our study included patients with SHL of sudden onset (occurring over a 72-hour period) at equal to or greater than 30 dB at three consecutive frequencies. Approximately one-third of cases are accompanied by complaints of tinnitus, dizziness, and ear fullness [2,3]. Risk factors associated with poor prognosis include time of disease progression prior to the initiation of treatment, extreme age (being very young or very old), severe initial hearing loss, concomitant vestibular symptoms, and a descending pure-tone audiometry curve [1,4,12]. The treatment regimen was the same as that used in group I patients, minus dextran or minus dextran and acyclovir if the SHL onset was greater than 5 days. Serological tests were also conducted for herpes simplex virus type I, cytomegalovirus, syphilis, rubella, measles, Lyme disease, and the human immunodeficiency virus.
Nevertheless, none of those authors compared their results with the prevalence observed in epidemiological studies of upper-airway infection in the corresponding populations. However, those authors found that prevalence of these disorders among patients with SHL was lower than that reported for patients with dizziness [15], which is in agreement with the findings by Cadoni et al.


In our study, the etiology was vascular in 4.3% of the cases of SHL, one of which was very severe. We cannot state with confidence that the likelihood of complete recovery is greater in such cases of SHL, as other factors such as gender and age at SHL onset might exert some influence.
In groups I, II, and III, treatment was initiated within the first 15 days after the onset of SHL.
We observed a genderbased difference in ΔPTA, with a tendency toward statistical significance, suggesting that the SHL prognosis is poorer for men.

Although Meniere's disease can affect people of any age, people in their 40s and 50s are much more likely to experience it. People with Meniere's will generally experience episodes in clusters with long periods of remission. The same could be said of biotech and pharmaceutical companies, as seen in treatments for otic disorders. Patients who take narrow therapeutic index drugs face higher risks than those who don’t because risk to patient health is higher with such drugs. Treatments for otic disorders of the outer ear are common, simple procedures, but treatments for otic disorders of the middle and inner ears are complex and often controversial.
The ear is made of three parts, the outer, middle and inner, and otic disorders can occur in all three.
These two approaches to microencapsulation are matrix encapsulation and core-shell encapsulation. Only 2 patients had improvement of hearing (from severe to normal, mild to normal), keeping unchanged all other results and no worsening (Table 2 and Figure 2). Patient 8, 73 years, has hypertension and diabetes, as well as probable hearing loss due to presbycusis before the episode of sudden deafness. In group B, eight patients (80%) treated with conventional therapy showed a reduction of subjective tinnitus and hearing score also improved in eight patients (80%) - the hearing remained unchanged in two patients (20%). All patients in both groups had ear fullness and tinnitus in association with the onset of the SSHL.
One year after the onset of symptoms on the right side, the cochlear implant was performed, and resulted in a complete suppression of tinnitus after activating the implant. It was concluded that, according to the survey of tinnitus, the time factor is the most reliable item for subjective tinnitus. We divided patients into five groups by profile and treated them with dextran, dexamethasone, acyclovir, nicotinic acid, and papaverine hydrochloride (with or without vitamin A). Group III included patients who had a 6- to 15-day history of SHL and who were hospitalized and treated with the same treatment used in group I minus acyclovir. If no improvement occurred in the auditory threshold after 3 days, treatment was discontinued and the patient was discharged. No statistically significant difference was noted among the treatment groups in terms of audiometric progression determined by calculating the difference between the low- and high-frequency PTAs seen at baseline and after 180 days (Table 7). Owing to differences in design and population, we cannot directly compare our sample with theirs. However, despite advances, serological diagnosis remains difficult, as most tests are nonspecific and have a low accuracy rate [17].
Blood circulation in the inner ear is of the terminal type, the cochlear artery running from the base to the apex of the cochlea.
In that case, SHL was detected after an episode of aplastic anemia (severe erythrocytopenia and thrombocytopenia) resulting from prolonged use of a nonsteroidal antiinflammatory drug (potassium diclofenac used daily for more than 1 year to treat acne). To our knowledge, no previous studies have attempted to identify the etiologies that are most often associated with audiometric normalization in patients with SHL.
However, the greatest improvement in PTA was observed in group II patients, who were the only ones not treated by dextran. A recent study demonstrated a statistically significant association between less recovery of hearing loss and male gender [16].
This condition is considered to be chronic and there is no cure, but there are various treatment strategies that will minimize the effect on one's life and relieve symptoms. This part of the ear contains tiny sensors that resemble hairs and respond to the movement of fluid, or endolymph, through the area.
When you experience an episode of Meniere's disease, it is best to lie down and focus on one sole, non-moving object. Although it is a complex and difficult-to-treat condition, type 2 diabetes can be managed with insulin and other medications. The procedure is well tolerated and relatively easy to perform as outpatient procedure performed under local anesthesia (topical), general anesthesia can be avoided, most patients understand the concept of intratympanic therapy and easily accepts the proposed therapy. Regarding the THI scores, it ranged from 58 to 96, prior to initiation of therapy, 8-82 and 30 days after.
Such comorbidities could not justify the improvement in hearing thresholds after the proposed therapy. None of the patients experienced side effects from this treatment, and the authors concluded that this option can be beneficial as adjuvant therapy for hearing improvement in patients with PANSS, but cost factors are the main obstacles to the use of this therapy14.
However, these symptoms improved only in Group A, showing a significant relationship between recovery of hearing thresholds and improvement of aural fullness. Clinical improvement was also reflected by a decrease in the scores of questionnaires THI and VAS. The hearing recovery was determined by comparing the hearing levels before and after treatment and tinnitus was subjectively evaluated by using a questionnaire. Worldwide, SHL accounts for approximately 1% of all cases of deafness, and 15,000 new cases occur annually [1,4]. Patients were divided into five treatment groups on the basis of SHL duration and clinical profiles that indicated the use or absence of the current drugs prescribed.
Group IV included patients with a 16- to 30-day history of SHL and who were treated with the group I regimen minus dextran and acyclovir. However, the fact that the time to first medical visit was longer in our study might be attributed to patients' lack of knowledge concerning the symptoms or difficulty in patients' gaining access to treatment. In our sample, tinnitus was much more prevalent (95% of cases) and was often the main reason for the disturbance, leading us to recommend that future clinical trials investigate therapeutic possibilities in preventing and managing this symptom in SHL patients. In our sample, diagnoses were made by determining erythrocyte sedimentation rates and levels of antinuclear factor and rheumatoid factor.
Intracochlear hemorrhage can be revealed through the use of magnetic resonance imaging, showing the importance of this procedure in making the diagnosis [24]. The authors estimated that audiometric recovery resulting from treatment translated to an increase in mean PTA of approximately 25 dB, similar to what we observed for low-frequency PTA. However, we agree with Mattox and Simmons [25], who reported a fundamental difference between hearing losses at low frequencies and those affecting high frequencies, stating that low-frequency losses are more easily reversed.
Although some underlying diseases can impair innerear microcirculation and hinder clinical improvement of SHL, the comorbidities presented by patients in group II were not indicators of poor prognosis. The better prognosis in women merits further analyses, given a possible bias that might be related to indicators of good prognosis. According to the National Institutes of Health (NIH), roughly 50,000 to 100,000 people a year develop Meniere's disease. However, it should be emphasized again that in relation to complaints of tinnitus, it has undergone a significant change, in which catastrophic change of the degree to mild (Table 1). Given this, the authors suggested the use of cochlear implants as a possible therapy for tinnitus persisted after sudden deafness. We determined outcome as the difference between day-0 and day-180 pure-tone averages (PTAs).
Since SHL was first described 62 years ago [5], various etiologies have been proposed, including the infectious, traumatic, neoplastic, immune, ototoxic, vascular, ischemic, neurological, and metabolic. Group V included patients with more than a 30-day history of SHL who were treated with nicotinic acid, papaverine hydrochloride, and vitamin A. If audiometric improvement occurred, the treatment regimen was maintained for up to 10 days. Possibly these discrepancies in the prevalence of upper-airway infection accompanying SHL are the result of geographical differences. In two patients, the diagnoses were made based on a clinical history of vasculitis (Churg-Strauss syndrome) and thrombophilia, respectively. This was also observed in our study in which low-frequency PTA normalized in 28 cases as compared with 15 cases of high-frequency PTA normalization. In our study, dextran was not found to act as an adjuvant to dexamethasone or acyclovir in the treatment of SHL, as the patients presenting the best response to treatment were those in the group not treated by dextran.
We obtained an average difference of 38.6 points among patients who reported an improvement in tinnitus before and after the course of oral steroids and intratympanic. In group A, the OAE responses appeared simultaneously with the improvement in hearing levels in five patients (63%).
Referring to EVA, there was a change from 7 to 10 points before therapy and from 1 to 8 points after it, in relation to intensity. It was concluded that patients with hearing improvement PANSS (Group A) tend to have OAE responses and sensations of fullness in the ear and tinnitus improved almost simultaneously with the hearing improvement. We observed significant improvements in PTAs after 180 days of treatment and noted a significant linear correlation between time from SHL onset to initial visit and recovery. The low-frequency PTA was determined by averaging the pure tones of the 250-, 500-, and 1,000-Hz frequencies, and the high-frequency PTA was based on those of the 2,000-, 4,000-, and 8,000-Hz frequencies. In relation to the nuisance, there was a change from 7 to 10 points before and 0-08 points after therapy. We determined audiometric evolution of the responses in the different treatment groups by subtracting baseline PTA from final PTA (after 180 days of treatment). Pitkaranta and Julkunen [21] investigated the protein MxA (a specific marker of systemic viral infection) in patients with SHL and found evidence of viral etiology in 6.5% of the cases. The authors concluded that patients with poor hearing improvement tend to have absent OAE and ear fullness and tinnitus persisted.
In the treatment of SHL, dextran provided no more benefit than did dexamethasone or acyclovir. We found mumps (paramyxovirus) to be the most common etiology, although we did not test for influenza or parainfluenza. These discrepancies can be attributed to the difficulty of making the viral diagnosis, given that the time to the first medical visit (interval between the onset of SHL and blood collection) varied from study to study, which can influence seropositivity. Of note in our study and in a previous study [22] is that some of the patients presented seropositivity for the bacterium that causes Lyme disease.
