Otosclerosis occurs when a series of small bones (shown in brown above) in the Middle Ear grow abnormally.
Otosclerosis is when abnormal growth occurs in a series of bones located the Middle Ear that physically pass on the sensation of sound to the Inner Ear.
The condition usually affects the last bone in the Middle Ear called the Stapes located at the entrance to the Cochlea – the organ that senses sound. It often begins in early to mid-adulthood with women aged between 15 and 30 years more likely to develop the condition. If left untreated, Otosclerosis can cause the slow onset of a Conductive Hearing Loss, which can become more severe over time.
Treatment options for Otosclerosis can include wearing a Bone-Conduction Hearing Aid or a Bone Anchored Hearing Device to help manage the associated hearing loss symptoms.
Having ear surgery is another option to remove the hearing loss symptoms associated with Otosclerosis. The other surgical option is a Stapedotomy where only a segment of the Stapes is removed and a small hole drilled at the bottom and putting a piston-like prosthesis in place. Excessive wax and presence of foreign objects – Ear wax is a normal defense mechanism of the ear, but excessive earwax could also mean a bad thing. Ear hematoma- This condition is secondary to trauma to the ears and if left untreated could lead to cauliflower-shaped deformity. Perichondritis- The tissues surrounding the earlobe and cartilage get infected secondary to trauma to the ears and insect bites. Tumor (cancerous and non-cancerous) – Non-cancerous tumors in the outer ear should be surgically removed. Acute otitis media- It occurs as a complication of allergies and colds, which can be caused by virus or bacteria. Chronic otitis media- This is an infection in the middle ear that has been going on and on.
Mastoiditis- The mastoid process, a bony structure behind the ear is infected by a particular type of bacteria.
Benign paroxysmal positional vertigo- It is characterized by episodes of vertigo that usually happens if you change the position of your head. Labyrinthine fistula- The bony capsule in the inner ear has an abnormal opening, which leads to leakage of perilymph to the middle ear.
Labyrinthitis- This inner ear disorder is usually caused by a virus, but it can also be caused by bacteria. Otosclerosis- This condition can lead to sensorineural hearing loss and conductive hearing loss.
Tinnitus is characterized by ringing in the ears, but the sounds being heard vary from one person to another. Tinnitus affects people of all ages, but the condition is more prevalent in the elderly, especially people 50 years old and above.
Mastoidectomy Types of Mastoidectomy There are two major types of mastoidectomy: canal wall down (CWD) and canal wall up (CWU). Audiovestibular Test Battery Approach in Patients with Vertigo AIJOCREVIEW ARTICLEAudiovestibular Test Battery Approach in Patients with Vertigo Deepa A Valame, Preeti NandapurkarABSTRACT All audiological tests are site-of-lesion tests and are used as a part of a test battery.
Meniere's Disease is thought to be triggered by immune reactions, metabolic disturbances within the inner ear, inner ear infections or trauma, possible allergic conditions, and other injures to the inner ear. Hearing loss is generally most pronounced in the lower frequencies and is accompanied by a distinct sensation of pressure, fullness or a stopped-up feeling in the ear. Sea shell-like roaring, ringing or bell-like noises in the ear (tinnitus) can be extremely distracting and bothersome. The clinical symptoms of Meniere's disease are thought to be caused by an increase in the fluid pressure within the delicate membranes of the inner ear. The classic theory is that during a Meniere's spell, the delicate membranes within the inner ear (cochlea) rupture. Unfortunately, the sudden disruption of the normal inner ear tissues leads to injury of the tiny hair cells that are responsible for hearing and balance. In some patients, Meniere's disease is only intermittently bothersome and takes an overall mild course. Periods of increased symptoms, which are unpredictable and occur without warning, may be followed by long periods of improvement or even complete remission.
Some blood tests are available to help rule out autoimmune inner ear disease that may simulate Meniere's Disease. The history and quality of symptoms are very important in making the diagnosis of Meniere's disease. On physical examination, the eardrums and neurological exam are usually normal, especially between the acute episodes of dizziness.
A new test, vestibular evoked myopotentials, VEMP, are now being used to test patients who are suspected of having Meniere's Disease. High resolution CT scans may be performed to rule out superior semi-circular dehiscence syndrome (SSCDS). Measurements of hemoglobin, blood sugar (glucose), cholesterol, immune system status, liver, kidney, thyroid function testing, and testing for infectious diseases such as syphilis, lyme disease, and infectious mononucleosis may be among the studies needed to rule out other conditions that may cause symptoms similar to those found in Meniere's disease. Medical treatment is directed towards decreasing the frequency of attacks, stabilizing the hearing, and managing the episodes of vertigo when they occur. Medication(s) may be prescribed to reduce the severity of symptoms and possibly to decrease the frequency of Meniere's spells.
A recent treatment for patients with Meniere's Disease that is effecting both ears (Bilateral Meniere's Disease) is the administration of oral methotrexate in low, weekly doses.
Vestibular (balance) rehabilitation programs may be useful in helping to adjust to the loss of balance function that is often seen in more advanced cases of Meniere's disease. Endolymphatic sac decompression is a surgical procedure performed to treat intractable Meniere's disease. Other surgical procedures are available to treat Meniere's disease but must be tailored to the patient's individual needs and circumstances. For most patients with Meniere's Disease, a combination of lifestyle changes and medication leads to significant improvement. In the last few years, a minimally invasive procedure has been developed that can lead to a significant relief of vertigo with less surgical risk. Gentamicin is a common antibiotic that has been used for many years to treat serious bacterial infections intravenously. Both of these medications can be toxic when the large doses are given orally or intravenously.
Middle ear perfusion treatment of the inner ear with these medications has been performed at both academic and clinical medical centers in the United States. The success of Middle Ear Perfusion has been aided by advances in carbon dioxide lasers, fiberoptic endoscopic technology, and high definition video imaging.
Dexamethasone seems to be most effective in patients with early Meniere's disease who have tinnitus, fluctuating hearing loss, and dizzy spells. Middle Ear Perfusion is a promising treatment for Meniere's disease that does not respond to medical therapy.

With Otosclerosis, the Stapes can ‘stick’ to the Cochlea’s entrance and interfere with the mechanical transfer of sound to the Inner Ear. This condition should be dealt with the soonest possible time or else fungi will start to thrive in the ear canal, which can further worsen the condition.
If you are suffering from perichondritis, then you should immediately consult your doctor for proper treatment and management.
On the other hand, cancerous tumors of the outer ear should be treated either by radiation or surgery. The cardinal signs of perforated eardrum are ringing in the ear, pain, bleeding in the ear, and hearing loss. This condition can be corrected by several maneuvers and these maneuvers should only be done by experts. Most labyrinthine fistula cases are congenital, but it can be developed with the passage of time.
Some patients hear buzzing, roaring, hissing, as well as whistling sound.  Tinnitus affects more than 50 million people all across the globe. The prevalence is also high in people who are exposed in extremely loud environment for a long period of time.


The mixing of inner ear fluids results in a sudden electrical discharge within the cochlea due to fluids with different electrolyte concentrations mixing together. It is possible that some, if not many, cases are due to a decrease in blood flow to the inner ear when the inner ear hydrostatic pressure prevents normal blood flow from reaching inner ear tissues. This study enables visualization of the structures of the inner ear and brain in order to rule out tumors, strokes, multiple sclerosis, hydrocephalus, congenital anomalies, and other abnormalities which can cause dizziness and imbalance. In SSCDS, there is an erosion of the normal bone that covers the top of the superior semi-circular canal. Ultimately, the patient and a skilled ear specialist must evaluate the history, physical examinations, entire clinical picture, and test results together in order to arrive at a diagnosis.
Regular exercise, adequate rest, and control of other medical problems may be helpful as well. In this transmastoid surgical procedure, an incision is made behind the ear, and the mastoid bone is entered. One procedure involves cutting the balance nerves (Vestibular Nerve Section) which is a neurosurgical procedure. However, some individuals will continue to have disabling symptoms in spite of comprehensive medical therapy. This procedure involves the use of a carbon dioxide laser, small fiberoptic telescopes, and placement of steroids or ototoxic medication through a very small opening made in the eardrum. In an outpatient surgical center setting using intravenous sedation, a local anesthetic is used to numb the ear canal and the eardrum.

Right Middle Ear: Mucosa removed from round window niche, exposing the round window membrane. Right Eardrum: Paparella Type I tube to aid in delivering additional doses of medication to the middle ear. It is performed on an outpatient basis and appears to be safe, is much less invasive than older surgical techniques, and will hopefully benefit many patients who have either failed conservative medical management or who require a more active approach to their condition.

If the abnormal bone growth extends into the Inner Ear, it can also cause Sensorineural Hearing Loss and affect balance.
What the doctor usually does is remove the excess ear wax with the help of a special instrument. The doctor will clean the canal and will use a specific antibiotic as well as acetic acid to prevent the infection from coming back. To confirm the presence of a hole in the eardrum, the doctor will assess the middle structure of the ear using an otoscope. This condition can be very painful and there is a possibility that you will lose your ability to hear. Anti-vertigo medications are usually given to patients with benign paroxysmal positional vertigo. To address this problem, various medical approaches should be used including prescription medication, lifestyle and diet modification, and surgery when deemed necessary.
There are also activities that can trigger labyrinthine fistula such as head trauma, pressure to the ears secondary to scuba diving, and exposure to a very loud noise. A lot of people think that tinnitus is a disease, but truth is that it is an indicator of an underlying disease condition. If you or somebody you know is suffering from tinnitus, you should immediately seek help because the condition gets worse over time. Speech audiometry, acoustic reflex testing and auditory brain stem response differentiate cochlear and retrocochlear sites of lesion. Meniere's Disease may be due to vessel inflammation (vasculitis), aging and narrowing of blood vessels, and additional unrecognized factors such as problems with calcium channel metabolism, etc. Classically, two muscles are used: (1) the sternocleidomastoid muscle (cervical VEMP or cVEMP) and (2) the inferior rectus muscle of the eye (ocular VEMP or oVEMP). The procedure is call "Laser Assisted Tympanotomy with Middle Ear Perfusion" or "LAT" for short.
Treating the inner ear with very small, strategically-placed doses of gentamicin takes advantage of this effect by inactivating the sensory cells that cause episodes of vertigo.
Once the eardrum is numb, a carbon dioxide laser beam focused through a microscope is used to perform a Laser Assisted Tympanostomy (LAT) - an extremely small, bloodless opening in the eardrum approximately 2-3 mm.

The eardrum has the ability to heal on its own, but there are times when surgery is needed. Hence, you should see your doctor right away so that you will receive all the necessary treatment and care.
Acute otitis media is usually treated with antibiotics as well as nonsteroidal anti-inflammatory drugs. The exact cause of tinnitus is still unknown up to this time, but the good news is that there are many different ways to manage this condition. Addition of cervical vestibular evoked myogenic potentials (VEMP) and ocular VEMP to this battery can further differentiate between saccular vs utricular lesions and between lesions of inferior vs superior vestibular nerve. Foster has proposed that increase fluid pressure within the cochlea (endolymphatic hydrops) causes a decrease in blood flow to cochlear and vestibular tissues. Genetic studies are being performed at The University of Iowa, Iowa City, IA as well as several other leading research centers.
Distension of the saccule of the inner ear in Meniere's Disease is what is being indirectly measured and porvides diagnostic potential. However, it has been found to have limitations such as not completely resolving the vertigo and sometimes leading to additional hearing loss. Three study groups were evaluated, each receiving a different number of doses of gentamicin. In case of trapped foreign objects, the doctor will manually remove the object using special equipment. To prevent infection, the doctor will prescribe antibiotic and will recommend keeping the ear dry. Overall, this battery of tests provides useful insights into the otoneurological diagnosis of vertigo.
However, there is considerable emotional pain when the disease is difficult to control, and the spells are unpredictable. Steroids, such as prednisone, can help reduce the severity of acute attacks but have significant side effects if taken for prolonged lengths of time. The procedure usually requires an overnight stay in an outpatient surgery center and is of relatively low risk. Overall study results showed control of vertigo in 75%, improvement in tinnitus in 48%, improvement in ear fullness in 62%, and hearing preservation in 90% of patients. Also included in a CWD mastoidectomy is widening the opening of the outer ear canal (a procedure known as meatoplasty).
However, we do not know what causes the increase in fluid pressure within the cochlea (increased production of inner ear fluid, decreased reabsorption of the fluid, or a combination of both). A fiberoptic examination of the middle ear and round window area is then performed using delicate 1.7 mm Middle Ear Endoscopes (lighted fiberoptic tubes) attached to a miniature television camera. Keywords: Vestibular evoked myogenic potentials, Auditory brain stem response, Acoustic reflex testing, Speech audiometry. Again, the hearing loss may be due to patchy areas of ischemic tissue within the inner ear secondary to a lack of adequate blood flow.


The round window is located and any scar tissue, adhesions, or obstructions that may be present are carefully removed.
This is called exteriorizing ear disease, and it makes ear diseases such as cholesteatoma safer by allowing an easy passage of disease out of the body. This makes subsequent invasion into deeper structures of the ear and skull much less likely. The role of audiovestibular testing in these patients is to ascertain degree of associated hearing impairment and to identify the site of lesion (whether cochlear or retrocochlear) leading to the vertigo and other associated symptoms like hearing loss, tinnitus, etc. Retrocochlear pathology refers to site of lesion at the VIIIth cranial nerve, cerebellopontine angle (CPA), or root entry zone of the nerve into the brain stem.1 All audiovestibular tests are topological and provide information about site of lesion and not the type of lesion. Further, each test assesses different site in the audio-vestibular system and is based on different principle thus assessing the system in a unique perspective. With a radical mastoidectomy, a CWD mastoidectomy is performed and the eardrum and middle ear bones are removed permanently.
This is further justified by Jerger's cross-check principle which states that the results of a single test must be cross-checked by an independent test measure.
When the results on independent tests correlate, it increases our confidence in the diagnosis and even when they do not agree, they further add to our understanding of the site and type of lesion.
The inclusion of tests in the battery depends on the sensitivity and specificity of the test in detecting the site of lesion.
These disadvantages include: the need for frequent ear canal cleaning, water restrictions and possible hearing changes. Following is a review of the contemporary audiological test battery used in evaluating patients with vertigo. The mastoid bowl or cavity created by a canal wall down mastoidectomy will often fill with earwax. The earwax must be removed periodically (approximately every 6 months) in order to prevent infection. Pure Tone Audiometry Pure tone audiometry (PTA) is the most basic test in audiological assessment.
Being a test of detection, it uses pure tones from 250 to 8000 Hz to estimate hearing thresholds.
An audiogram is a plot of hearing thresholds (in dB hearing level) obtained using air-conduction and bone-conduction tones as a function of frequency.
It thus provides ear-specific and frequency specific information about peripheral hearing status. It can indicate the degree of hearing loss, its type and configuration, thus being a starting point for conduction of further tests.
Patients with vertigo may present with different audiometric patterns upon the underlying pathology.
At times, even the earplug is not sufficient to prevent water from entering the mastoid cavity.
Pure vestibular disorders may present with normal hearing sensitivity whereas those with labyrinthitis may show profound hearing loss.
Meniere's disease may present with fluctuating low frequency sensorineural hearing loss (SNHL) in the initial stages when the loss accompanies the episodes of vertigo; later it may become a permanent flat SNHL. In these patients PTA is used as an outcome measure in glycerol testing for the diagnosis of the disease. Therefore, hearing may be diminished to some degree as a result in this change of architecture. Speech Audiometry It involves use of standardized speech samples to estimate various measures of performance like the speech recognition threshold (SRT), word recognition score (WRS), performance intensity function (PI function), most comfortable loudness level (MCL) and uncomfortable loudness level (UCL).
SRT is the lowest level at which a person can identify the stimuli as speech 50% of the times it is presented and is routinely determined using spondees, i.e. CWU surgery does not remove the bone of the ear canal or create a cavity that is exposed to outside air, as is done for CWD mastoidectomy. SRT-PTA agreement is an important diagnostic tool wherein SRT poorer than PTA is associated with presence of RCP.
Rather, the mastoid disease along with trabeculated bone is removed and tissues are closed back to their normal positions. WRS is the percentage of correctly identified monosyllabic words from standard word list and gives us an idea about the patient's ability to recognize speech at supra threshold levels.
This eliminates the need for mastoid bowl cleaning, and people usually return to normal activities. Poor WRS than would be expected based on audiometric configuration and severity is indicative of RCP.
Further, poorer WRS with increase in the intensity of speech stimulus or roll-over phenomenon is diagnostic of RCP. Patients with cochlear pathologies show fair to good SRT-PTA agreement, fairly good WRS and reduced dynamic range (UCL-SRT) due to lowered UCL.
Acoustic Reflex Testing It is an important test in the immittance test battery and plays an important role in the differentiation of cochlear lesions with RCP. Residual or recurrent ear cholesteatoma after canal wall up mastoidectomy may be hidden from ear canal inspection in the office by the wall of the ear canal.
For this reason, it is common to perform a second look surgery several months (typically 9 – 12 months) after the first surgery. The acoustic reflex threshold (ART) refers to the lowest intensity of the stimulus needed to elicit the reflex.
The second look operation is performed to determine if there is residual or recurrent cholesteatoma that otherwise would go undetected by examination in the office and even by X-ray (CT).
The reason for waiting several months after the first surgery is that, if residual or recurrent cholesteatoma is present, the cholesteatoma will often grow to a sufficient size that the cholesteatoma can be visualized surgically by 9 – 12 months. Operating too soon may mean that cholesteatoma will not have enough time to develop into a large enough size to be detectable.
Waiting too long, however, increases the chance that a residual or recurrent cholesteatoma will damage the ear. At the same time, the middle ear bones can be rebuilt, if it is felt that hearing could be improved. AR is absent 30% of persons with eighth nerve lesions with normal hearing whereas in 70% of persons with eighth nerve lesions with a mild 30 dB hearing loss.2 In persons with hearing loss greater than 75 to 80 dB, absence of reflex cannot be considered diagnostic of RCP thus leading to confounding results. Comparison of ipsilateral and contralateral reflex findings gives different reflex patterns thereby providing useful insights to the site of lesion decision. There is still a chance that chance that cholesteatoma can redevelop even if no cholesteatoma is found at the second look operation. Presence of acoustic reflex when stimulus presented to the ear with RCP is an exception rather than the rule.
For this reason, patients must still be followed for several years in the office to look for recurrent cholesteatoma. In such cases testing is done to find evidence of reflex decay: Relaxation of stapedius muscle during sustained presentation of reflex activator. A canal wall down mastoidectomy has a lower chance of recurrent cholesteatoma than a canal wall up mastoidectomy. Auditory Brain Stem Response Auditory brain stem response (ABR) is the result of synchronous neural activity of the 8th nerve and auditory brain stem, evoked in response to certain specific stimuli such as clicks.
Bioelectric activity, which may include the ABR, is picked up from the scalp and processed to enhance the response and minimize the background random EEG activity.
Jewett and Williston4 were the first to record systemically these responses from the scalp of human subjects to various stimulus and recording parameters and to suggest its clinical utility.
Judgement of such a response, accurate identification of various peaks and their measurements generally have very high reliability (cases with retrocochlear sites of lesion are a major exception which itself will be of diagnostic significance).
Jagadeesh and Gore5 proposed several indices based on empirical considerations for the differentiation of cochlear vs retrocochlear sites of lesion as summarized below. Also using ABR, 'silent' plaques of multiple sclerosis were demonstrated,6 brain stem death could be ascertained7 and altered myelin development in childhood.8 Currently the role of ABR is not as relevant for detection of such abnormalities because of the availability of imaging methods like magnetic imaging that can identify tumors measuring few mm. Lutman10 suggested that ABR may be considered primarily a screening test for acoustic tumors.
According to him the preferred diagnostic tests for patients suspected of a CP angle tumor were high-resolution CT, or preferably MRI.
If these tests are not readily available, patients with normal ABR results might forego imaging studies. Stacked ABR may be used to increase the sensitivity of ABR to identify smaller lesions not picked up in conventional ABR. They recorded the potentials with surface electrodes placed on the sternocleidomastoid (SCM) muscle and with high quality EMG recording techniques; they showed the responses to be repeatable. They studied VEMP findings in three patients before and after selective sectioning of the vestibular nerve on one side and found absence of VEMP on ipsilateral side but VEMP were preserved in subjects with severe to profound hearing loss thus concluding that the vestibular afferents to be important in mediating VEMP.
