Besides a stoppage of drainage pathways, abnormally enlarged fluid pathways into the ear such as the vestibular aqueduct or cochlear aqueduct may also be associated with Meniere's like symptoms. Thus, the bottom line is that in most patients with Meniere's disease in 2015, the underlying cause of Meniere's disease is unknown.

When there is sulfa allergy, one may try amiloride by itself, or ethacrinic acid (edecrin). Histamine injections (irrational treatment as histamine is broken down rapidly in the body).
What the author recommends in his practice in Chicago for medical prevention of Meniere's. These are combined with symptomatic drugs such as meclizine, benzodiazepines, and antiemetics, to be taken during attacks. In persons with severe progressive bilateral disease, the author will generally recommend a trial of high dose steroids. An emerging treatment that may eventually end up as a standard treatment is multiple injections of steroids into the middle ear. The big problem with this section is separating placebo's from slightly effective treatments. There are an immense number of placebo and probable or nearly placebo treatments for Meniere's disease. The Meniett device's status at this writing (2010) seems most likely to be a slightly effective treatment. There is a separate page on this topic, but briefly, for intractable unilateral Menieres disease cases, we often presently advise a low dose gentamicin protocol.
Persons who have intractable bilateral Meniere's disease are offered a trial of steroids with a safer immunosuppressant should this be effective, a modified gentamicin protocol, and very occasionally systemic aminoglycosides to deaden both ears.
In our opinion, medical treatments, including a reasonable trial of anti-migraine drugs such as verapamil or venlafaxine, should precede use of any last resort treatment. Hearing is thought to gradually decline throughout life, with roughly 50 dB loss in 10 years.
Note that it is not the overall level of sodium that is important, but whether or not it fluctuates that is important in avoiding attacks of dizziness.

In our clinical practice, where we care for large numbers of Meniere's patients, the most common age of presentation is in the 6th decade. While in the past, it was felt that plumbing problems (hydrops) in the ear were responsible for the disease, the most current opinion is that hydrops is a marker for the Meniere's disease, rather than necessarily being responsible for the symptoms. Recent evidence is against a relationship between the cochlear aqueduct and MD (Yilmazer et al, 2001). We ourselves hold this opinion, based in part on a study in which patients with Meniere's disease had a very high prevalence (about 25%) of autoimmune thyroid disease (Brenner et al, 2004). However, the evidence is against this being the main mechanism in human beings (see Kitamura et al, 1997; Nadol et al, 1995).
Those who present to the doctor with more severe hearing impairments at onset, usually do worse than those who have milder hearing impairments (Sato et al, 2014). Although Ondansetron isn't as strong as phenergan or compazine, and doesn't always work, it also doesn't have much side effects either. All of the above diuretics have sulfa in them, which persons with sulfa allergies may be unable to tolerate. Loop diuretics such as Edecrin should be used in low doses and with caution because they are ototoxic. If there is a significant improvement in hearing, then there is an attempt to switch to Enbrel (an immunosuppressant with less side effects than steroids), with the thought that in this situation an autoimmune disorder is more probable. There is nothing wrong with a placebo, if it provides some benefit (presumably psychological), and you can afford to do this. This treatment requires a surgical procedure (insertion of a ventilation tube) and purchase of a very expensive device (the pressure machine). Gentamicin is administered through the ear drum every month for a total of one or two administrations. The difficulty in pregnancy is that there should be an effort to avoid medications that might cause birth defects or otherwise injure the unborn child.


Vertigo spells are generally thought to persist for decades, although with a gradual decline after roughly the first decade (Huppert et al, 2010). It is not necessary or wise to lower your salt intake to amounts barely able to sustain life.
Psychological characteristics of patients with Meniere's disease compared with patients with vertigo, tinnitus or hearing loss. Current treatment to restore hearing is centered on the use of auditory prostheses; however, no current option is able to fully restore normal hearing (dashed line). The inner ear begins as an undifferentiated patch of ectoderm adjacent to the hindbrain at embryonic day (E) 8. Upon activation of Notch by Jagged or Delta, the Notch IntraCellular Domain (NICD) is cleaved by ?-secretase.
Max forms a heterodimer with Myc but is also capable of forming a heterodimer with the Mad family of antagonists. We began our exploration of N-Myc and L-Myc function following our stated hypothesis that N-Myc and L-Myc were important to proliferation and possibly followed similar pathways in the inner ear as the Mycs had been described to elsewhere in the body.
Regeneration of lost organ of Corti hair cells through forced cell cycle re-entry of supporting cells or through manipulation of stem cells, both avenues towards a permanent cure, require a more complete understanding of normal inner ear development, specifically the balance of proliferation and differentiation required to form and to maintain hair cells.
We think Meniere's disease should more properly be called Meniere's syndrome, but we will use the two terms as if they were the same.
This probably reflects the age distribution of Meniere's in Chicago Illinois, which of course is also a function of the age of the population in Chicago. Enlarged vestibular aqueducts are one of the most commonly identified inner ear bony malformations in children with sensorineural hearing loss of unknown cause (Oh et al, 2001). On the other hand, Ruckenstein and others recently obtained a large number of autoimmune blood tests in a group of 40 patients with unilateral Meniere's disease including CBC, ANA, Anti-Sjoegren, RF, Complement, antiphospholipid antibody, western blot for heat shock protein, MHA (syphilis test), and Lyme.
Rather, it seems that Meniere's disease damages both hair cells and nerve fibers in humans. Should MRI scanners become even more powerful in the future, this could be an important test. Oddly, there is sometimes a discrepency between OAE tests and audiometry in the low-frequency SNHL of Meniere's. Van Deelen and Huizing studied the use of diuretics in Meniere's disease in a double-blind, placebo controlled trial, and reported that it reduces vestibular complaints, but has no significant effect on hearing (1986).
Because Menieres and Migraine are very often combined, this medication's main role may be to treat the migraine associated vertigo that can be confused with or accompany Menieres disease. Of course this strategy should rationally be adjusted to the variability in hearing, as in any undertaking, one's confidence that a particular result has been obtained depends both on the size of the effect as well as the underlying variability in the effect.
However, we don't think that placebos that are billed to health care insurance providers should be supported. Bilaterality of the condition gradually increases with time, but in most the symptoms in the opposite ear are minor. Sound waves hit the ear drum and are turned into physical vibrations that are propagated through three middle ear bones, the malleus, the incus, and the stapes.
Thus, perfect solutions to this growing problem include prevention of hair cell loss and when hair cell loss does occur, regeneration of damaged tissue is needed to restore full functionality. Through induction by diffusible factors such as the Wnts and Fgfs, neuroectoderm is formed. NICD translocates to the nucleus to form a complex with RBPJ to positively regulate the transcription of the Hes family of bHLH TFs [63].
While the full mechanisms require further elucidation, we have provided some clarity to the picture. Direct successful alterations to the cell cycle result in cell death whereas regulation of upstream genes is insufficient to permanently alter cell cycle dynamics. It is a little older than the typical age of presentation of vestibular migraine which is in the 5th decade, much older than the reported highest prevalence age for non-vestibular migraine (about 35), and similar to the age of presentation of BPPV.
The vestibular aqueduct extends from the medial wall of the vestibule to the posterior surface of the petrous temporal bone. Only elevations in the antiphospholipid antibody test were found 27% of patients, above the expected 6-9%.
Studies of humans are handicapped by the possibility that Meniere's is the final common pathway of a variety of illnesses of the ear.
Potential reasons are an exitatory nystagmus, Bechterew's phenomenon (recovery nystagmus), Meniere's involving the opposite ear, and stronger vestibular responses on the side with hydrops due to hydrodynamic factors associated with hydrops.
Another new MRI approach involves injecting gadolinium through the ear drum, and then a MRI scan (Gu et al, 2014). The same cannot always be said for meclizine, lorazepam and klonazepam, phenergan or compazine.
Much room for improvement in these algorithms is needed -perhaps involving daily hearing monitoring using an internet protocol. The treatments briefly discussed below are (probably) not placebos, but they are high in cost (because they are surgical), and low in benefit (because the literature suggests low or no efficacy).


The stapes articulates with the oval window, which separates the middle ear from the inner ear’s fluid-filled scala vestibuli. To successfully prevent the loss of hair cells or regenerate hair cells after loss, we must have a greater understanding of the molecular basis of ear development, specifically, what genes are needed to form and to maintain hair cells. The Myc gene family is uniquely situated to synergize upstream pathways into downstream cell cycle control. Most persons with enlarged vestibular aqueducts with ear disorders have hearing loss, but occasionally there is an association with vestibular problems (Shessel and Nedzelski, 1992). This technique is plausible, but we are doubtful that the diagnostic gain justifies injecting gadolinium dye into the middle ear. Kundu (2006) were unable to come to a conclusion as to efficacy as no papers published up to 2006 were adequate for meta-analysis. Physical vibrations of the middle ear bones are converted into compression and rarefaction of the perilymphatic fluid. Upon elucidating these minimal essential factors, it may be possible to directly target inner ear tissues. Once activated, Myc interacts with partner proteins to regulate a number of downstream effectors, including the cyclins, E2Fs, IDs, CDKIs, and various microRNAs. There may be a genetic link between enlarged vestibular aqueduct and Pendred syndrome, which is a congenital thyroid disorder. They concluded that it is unlikely that autoimmune etiologies play a significant role in their population of unilateral Meniere's (Ruckenstein, 2002). In the case of prevention, increasing the hair cell’s natural maintenance mechanisms may be sufficient. An initially small population of NS precursor cells undergoes symmetric division leading to additional NS precursor cells. This regulation leads to the inhibition of class II bHLH TFs from binding to the E-proteins which then allows the Hes family to occupy the E-proteins.
The function of the two ear expressed Mycs, N-Myc and L-Myc were unknown less than two years ago and their therapeutic potentials remain speculative.
Another interpretation of their data is that they may simply not have had an appropriate marker for autoimmune involvement, as well as unilateral Meniere's may have less autoimmune cause than bilateral. As the fluid waves propagate through the scalae, they cause vibrations of the overlaying basilar membrane. Once hair cells are lost, manipulation of inner ear supporting cells may be possible to form new hair cells. In this review, we discuss the roles the Mycs play in the body and what led us to choose them to be our candidate gene for inner ear therapies. This vibration results in a shearing force of organ of Corti hair cells against the tectorial membrane to activate the auditory nerve (A). On the other hand, an alternative source of cells, such as stem cells could be first manipulated to form hair cell-like cells and then targeted to the damaged tissue to restore hearing.
At a certain point, tumor suppressor genes, pro-sensory genes, and pro-neural genes increase leading to the asymmetric division of NS precursor cells into differentiated NS cells. IDs are able to bind bHLH TFs but since they lack a basic motif, are unable to bind E-boxes, inhibiting differentiation. We will summarize the recently published work describing the early and late effects of N-Myc and L-Myc on hair cell formation and maintenance. The formation of NS cells such as neurons and hair cells help maintain the differentiated state of nearby supporting cells.
In the absence of IDs or cyclins, bHLH TFs are free to bind to E?proteins and the E-box, promoting differentiation. Lastly, we detail the translational significance of our findings and what future work must be performed to make the ultimate hearing aid: the regeneration of the organ of Corti. The differentiated state is further maintained by high levels of cyclin dependent kinase inhibitors (CDKIs) and retinoblastoma (Rb).
Red indicates pathways favoring differentiation, blue indicates pathways favoring proliferation.
In conductive hearing loss (B), sound waves are not accurately propagated to the inner ear.
Hearing aids (E) can partially overcome the resulting hearing deficit by increasing the amplitude to nearby cells; however, no hearing aid can stimulate lost hair cells and furthermore, hearing aids may create discomfort by over-stimulating remaining hair cells. The best current treatment for sensorineural hearing loss is cochlear implants (F) which directly stimulate auditory neurons through an electrode array surgically implanted into the inner ear.
