Meniere’s disease is a chronic illness that affects a substantial number of patients every year worldwide. Fluctuating, progressive, unilateral (in one ear) or bilateral (in both ears) hearing loss, usually in lower frequencies. Nausea, vomiting, and sweating sometimes accompany vertigo, but are symptoms of vertigo, and not of Meniere's. Some sufferers also experience nystagmus, or uncontrollable rhythmical and jerky eye movements, usually in the horizontal plane, reflecting the essential role of non-visual balance in coordinating eye movements.
The American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium (AAO HNS CHE) set criteria for diagnosing Meniere's, as well as defining two sub categories of Meniere's: cochlear (without vertigo) and vestibular (without deafness). The center of production for endolymph is a structure in the cochlea called the stria vascularis. Although its pathogenesis has been proposed to be a disorder of water transport in the inner ear, subsequently, it remains unsolved, until now.

Meniere's disease is idiopathic, but it is believed to be related to endolymphatic hydrops or excess fluid in the inner ear. Other possible conditions that may lead to Meniere's symptoms include syphilis, Cogan's syndrome, autoimmune disease of the inner ear, dysautonomia, perilymph fistula, multiple sclerosis, acoustic neuroma, and both hypo- and hyperthyroidism. The unpredictable episodes of vertigo are usually the most debilitating problem of Meniere's disease. Meniere’s disease is a chronic disorder of the inner ear involving sensorineural hearing loss, severe vertigo and tinnitus.
Meniere’s disease appears to involve overproduction or decreased absorption of endolymph, with resultant degeneration of vestibular and cochlear hair cells. Recurrent attacks result in progressive sensorineural hearing loss (especially low tones), usually unilateral in nature.
Goal of treatment may include recommendations for changes in lifestyle and habits or surgical treatment.
Psychological evaluation may be indicated if patient is anxious, uncertain, fearful or depressed. Tranquilizers and antihistamines such as meclizine (Antivert) to control vertigo and to suppress the vestibular system; antiemetics for nausea and vomiting. Impaired adjustment related to disability requiring change in lifestyle because of unpredictability of vertigo. Risk for fluid volume imbalance and deficit related to increased fluid output, altered intake, and medications.
Anxiety related to threat of, or change in, health status and disabling effects of vertigo. Ineffective coping related to personal vulnerability and unmet expectations stemming from vertigo.
Discuss medications that may be prescribed to prevent attacks or self-administration of appropriate medications during an attack, which may include anticholinergics, vasodilation, antihsitamines, and possibly, diuretics or nicotinic acid.
A labyrinthectomy is the most radical procedure and involves resection of the vestibular nerve or total removal of the labyrinth performed by the transcanal route, which results in deafness in that eat. Audiogram shows flat sensorineural hearing loss at 60 db, typical of late Meniere's disease.
VEMP shows preserved responses on both sides, the left being moderately better than the right.
One would think that for the first explanation, head-shaking might also be reversed (as was seen here).
A third and very recent explanation is that the enlarged endolymphatic passages in the bad ear cause a relative increase in force exerted on the cupula, and excitation.
According to US government statistics from the 60's (National Center for Health Statistics), only 8% of the entire US population has any difficulty with hearing at all. Examples of conditions that cause sensorineural hearing loss are noise and just living a long time. If you have a sensorineural hearing loss, your goal should be to find out why, if you can prevent it from getting worse, and if a hearing aid could help you in overcoming the impairments associated with hearing loss.
If you have to have a hearing loss, it is best to have a conductive one, as these disorders are often fixable. If you have a conductive hearing loss, your goal should be to find out why, if you can prevent it from getting worse, and if a hearing aid, surgery, or perhaps just wax removal might help you in overcoming the impairments associated with hearing loss.

Leskowitz MJ1, Caruana FF2, Siedlecki B2, Qian ZJ1, Spitzer JB2, Lalwani AK2.Asymmetric hearing loss is common and benign in patients aged 95 years and older. Vice President of Audiology and Professional Relations, OticonDon Schum currently serves as Vice President for Audiology & Professional Relations for Oticon, Inc. When viewed within the broader context of life change, it is not surprising that so many older adults resist the idea of using hearing aids. This course discusses the relationship between expected outcome and satisfaction with the hearing aid process. Improving speech understanding, especially in complex listening environments, is clearly the main focus in hearing aid fittings for patients with sensorineural hearing loss. Effective speech understanding in environments with multiple sources of sound is the greatest challenge for those with sensorineural hearing loss. This is the first in a series of 4 seminars that will examine the way current and future signal processing works within realistic, everyday contexts. As an overview, low frequency (or tone) sensorineural hearing loss (LF SNHL or LT SNHL) is unusual, and mainly reported in Meniere's disease as well as related conditions such as low CSF pressure.

Le Prell et al (2011) suggested that low frequency hearing loss was detected in 2.7% of normal college student's ears.
Oishi et al (2010) suggested that about half of patients with LTSNHL developed high or flat hearing loss within 10 years of onset. The new international criteria for Meniere's disease require observation of a low-tone SNHL. Gatland et al (1991) reported fluctuation in hearing at low frequencies with dialysis was common, and suggested there might be treatment induced changes in fluid or electrolyte composition of endolymph (e.g. Although OAE's are generally obliterated in patients with hearing loss > 30 dB, for any mechanism other than neural, this is not always the case in the low-tone SNHL associated with Meniere's disease. The lack of universal correspondence between audios and OAE's in low-tone SNHL in at least some patients with Meniere's, suggests that the mechanism of hearing loss may not always be due to cochlear damage.
Of course, in a different clinical context, one might wonder if the patient with the discrepency between OAE and audiogram might be pretending to have hearing loss.
Papers are easy to publish about genetic hearing loss conditions, so the literature is somewhat oversupplied with these. Bespalova et al (2001) reported that low frequency SNHL may be associated with Wolfram syndrome, an autosomal recessive genetic disorder (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness). Bramhall et al (2008) a reported that "the majority of hereditary LFSNHL is associated with heterozygous mutations in the WFS1 gene (wolframin protein).
Eckert et al(2013) suggested that cerebral white matter hyperintensities predict low frequency hearing in older adults. Fukaya et al (1991) suggested that LFSN can be due to microinfarcts in the brainstem during surgery.
Ito et al (1998) suggested that bilateral low-frequency SNHL suggested vertebrobasilar insufficiency.
Yurtsever et al (2015) reported low and mid-frequency hearing loss in a single patient with Susac syndrome. There are an immense number of reports of LTSNHL after spinal anesthesia and related conditions with low CSF pressure. Fog et al (1990) reported low frequency hearing loss in patients undergoing spinal anesthesia where a larger needle was used.
Waisted et al (1991) suggested that LFSNHL after spinal anesthesia was due to low perilymph pressure.
Wang et al reported hearing reduction after prostate surgery with spinal anesthesia (1987). We have encountered a patient, about 50 years old, with a low-tone sensorineural hearing loss that occured in the context of a herpes zoster infection (Ramsay-Hunt). LTSNHL is generally viewed as either a variant of Meniere's disease or a variant of sudden hearing loss, and the same medications are used.

The disease is characterised by intermittent episodes of vertigo lasting from minutes to hours, with fluctuating sensorineural hearing loss, tinnitus, and aural pressure. It is diagnosed based on the presence of a cluster of symptoms which may not occur in unison, making it less likely for a physician to make the diagnosis. However, a detailed otolaryngological examination, audiometry and head MRI scan should be performed to exclude a tumour of the eighth cranial nerve or superior canal dehiscence which would cause similar symptoms.
Once the endolymph is created it is distributed throughout the scala media of the cochlea, and is then absorbed into the endolymphatic duct and sac. A recent study revealed that both plasma stress hormone, vasopressin (pAVP) and its receptor, V2 (V2R) expression in the inner ear endolymphatic sac were significantly higher in Meniere's patients. The episodes often force a person to lie down for several hours and lose time from work or leisure activities, and they can cause emotional stress. One study found that 15 of 47 patients with Meniere’s disease who had failed to respond to previous treatments improved with B6 (pyridoxine). In addition, on bad days, using a B-complex several times a day instead of only once can help also. The treatment is designed to eliminate vertigo or to stop the progression of or stabilizes the disease. This explanation doesn't really explain spontaneous nystagmus, but it might explain asymmetric high-velocity VOR. Furthermore, only 3% of the population had difficulty hearing anything other than faint speech. Adults with hearing loss are more likely to be unemployed and earn less wages (Jung and Bhattacharyya, 2012).
If we do the math, 90% of 8% of the population with a hearing loss works out to about 7% of the population. Persons with cochlear deficits fail OAE testing, while persons with 8th nerve deficits fail ABR testing. If we do the math again, as only 8% of the population has a hearing loss at all, and 90% of them are sensorineural, this means that only 0.8% of the population has a conductive hearing loss.
Central hearing loss generally isn't helped to a great extent by medication or surgery, but preventing progression is important. Sudden hearing loss as well as Congenital hearing loss may be due to sensorineural, conductive or central mechanisms. Association of hearing loss with decreased employment and income among adults in the United States .Ann Otol Rhinol Laryngol. Previous to his position at Oticon in Somerset, Don served as the Director of Audiology for the main Oticon office in Copenhagen Denmark. This seminar examines techniques developed by related professions in encouraging the older patient to be willing to make a health care change. Given the inherent limitations imposed by sensorineural hearing loss, there will be limits to how well a newly fit patient will be able to perform with amplification. It is essential then that the professional have a comprehensive appreciation for the nature of the speech signal and the effects of amplification. A variety of technologies have been developed or are currently under investigation to address these complex situations.
Many professionals have an inaccurate understanding of how approaches such as noise reduction, directionality, open fittings, real ear analysis, etc.

To us, this seems a little overly stringent, compared to the earlier 1995 AAO criteria that just required any kind of hearing loss, but criteria are better than no criteria.
That being said, genetic conditions should not be your first thought when you encounter a patient with LTSNHL. One would think that diabetes insipidus is so rare that hearing loss is probably not the main reason these individuals are seeking attention. These patients are extremely rare because there isn't much microsurgery done close to the brainstem. We are dubious about the conclusion of this paper because it is different than nearly every other paper in the literature. We are dubious that this has any applicability to humans and we have never seen a patient with lithium toxicity with any LFSNHL. We have observed this occasionally ourselves, but of course, the usual pattern is a conductive hyperacusis. We find this somewhat plausible as pregnancy and delivery might be associated with spinal anesthesia, with changes in collagen, and with gigantic changes in hormonal status. Although there is currently no cure, more than 85% of patients with Meniere’s disease are helped by either changes in lifestyle and medical treatment, or minimally invasive surgical procedures such as intratympanic steroid therapy, intratympanic gentamicin therapy, and endolymphatic sac surgery. Meniere’s disease appears to predominantly affect adults around the age of 40 years, with a range of onset between 20-60 years.
There is no definitive test for Meniere's, it is only diagnosed when all other causes have been ruled out. The endolymphatic sac of Meniere’s patients can malfunction, thus not allowing the endolymph to be reabsorbed. Three patients failed to improve and others gradually improved but it was uncertain whether pyridoxine supplementation was responsible. In US data between 1988 and 2006, mild or worse unilateral hearing loss (25 db or worse), is reported in 1.8% of adolescents.
If you are older, statistics say that while many of your older associates may have the same problem, it will probably get worse, so you should prepare yourself and do your best to slow down the rate that it gets worse. In addition, he served as the Director of the Hearing Aid Lab at the University of Iowa, School of Medicine (1990-1995) and as an Assistant professor at the Medical University of South Carolina (1988-1990).
However, satisfaction with the process can still be high, especially if the focus is placed on the professional care provided by the audiologist. Much of what we do in hearing aid fittings is based on attempts to maximize effective audibility for the patient. However, in order to appreciate what these current and future technologies can actually offer our patients, it is essential to have a realistic understanding of how these technologies address complex environments. There is a large literature about genetic causes, mainly in Wolfram's syndrome ( diabetes insipidus, diabetes mellitus, optic atrophy, and deafness), probably because it is relatively easier to publish articles about genetic problems. He defined LTSNH as that the sum of the three low frequencies (125, 250, 500) was more than 100 dB, and the sum of the 3 high frequencies (2, 4, 8) was less than 60 dB.
In other words, Wolfram's is probably not diagnosed mainly by ENT's or audiologists, but rather by renal medicine doctors, as DI is exceedingly rare, while LTSNHL is not so rare in hearing tests. That being said, it is very rare to encounter any substantial change in hearing after pregnancy.
Vestibular neurectomy has a very high rate of vertigo control and is available for patients with good hearing who have failed all other treatments. The disorder does affect a small number of children younger than 20 years, and these cases comprise around 3% of all Meniere’s cases. An endolymphatic sac blockage can cause the endolymph volume to increase along with the pressure within the cochlea. Furthermore, 23 patients with vertigo due to unknown causes received pyridoxine and many of them responded.
There was greater risk in individuals with work exposure to loud noises, lower socioeconomic background and in ethnic minorities. Other things that cause conductive hearing losses are fluid in the middle ear, and disorders of the small bones (ossicles) in the middle ear.
Although this approach has served us well up to this point in time, further improvements in patient performance will require a more sophisticated approach to managing the speech signal.This is the second course in a seminar series on AudiologyOnline in 2010 by Dr. In addition, speech-based signal processing approaches that have been developed by other industries or have been investigated in research labs could conceivably make their way into hearing aids at some point in the future. Roughly speaking, the frequency patterns of hearing loss are divided up into: Low-frequency, mid-frequency, high-frequency, notches, and flat. Labyrinthectomy is undertaken as a last resort and is best reserved for patients with unilateral disease and deafness.
Schum has been an active researcher in the areas of Hearing Aids, Speech Understanding, and Outcome Measures. Schum that examines the truths that we sometimes take for granted when we go about the task of fitting patients with amplification.
Now is as a good a time as any for the audiologist to begin to see how these systems work and how they can be applied to help those with hearing loss.
The natural biochemical mechanism for relieving this endolymphatic sac blockage is to release hormones which cause an increase in endolymph, creating even more hydraulic pressure in the cochlea. For more information on other courses in this series, visit the AudiologyOnline course library. Morrison found an autosomal dominant inheritance pattern with 61% penetrance for 41 families. Eventually there is a release of this endolymphatic sac blockage, allowing the pressure of the cochlea as well as the endolymph volume to return to baseline. This pressure release is responsible for the vertigo symptoms that occur during a full-blown Meniere’s attack.
