Ménière disease (MD) is a chronic illness of the inner ear that affects a substantial number of patients every year worldwide. Because of a dearth of well-controlled studies, the medical and surgical management of MD remains quite empirical. The main reason is that it is very difficult to investigate patients affected with Certain MD due to the post-mortem criterion necessary for this diagnostic grade. Although Endolymphatic Hydrops (EH) is the worldwide accepted mechanism of MD, the causes that induce it are still not clear. In fact MD has been correlated mostly to a wide and different disturbances ranging from trauma to sleep disorders. It is nowadays sufficiently demonstrated that Chronic Cerebro Spinal Venous Insufficiency (CCSVI) is very frequent in MD. Even if CCSVI may potentially induce EH through a pure hydraulic mechanism CCSVI, per se does not explain how the various disorders correlated with MD may interact with CCSVI and provoke EH. The aim of this review is an attempt to approach MD into the context of the more recent findings about the global brain waste clearance system, to which inner ear is anatomically and functionally connected, in order to build a reasonable model of MD pathogenesis. The major part of the diseases correlated to MD may act on the inner ear disturbing the Glymphatic (GS) and/or Brain Lymphatic System (BLS) activity. The venous system interplays with GS and BLS. In this model CCSVI is considered more than a direct cause of MD rather the anatomical predisposition to develop the disease. In this model EH, and then MD, is the consequence of a failure of the compensation of the congenital venous abnormalities, anatomical compensation as collateral pathways and/or functional compensation as GS and BLS. In this model the major part of the disturbances correlated to MD and the various treatment proposed find their appropriate placement.

Hypothesis: The endolymphatic hydrops (EH) does not affect hearing loss significantly at low frequencies, whereas the hydrops affects the diplacusis. Background: There have been many arguments whether the EH cause the Meniere disease. Despite a lot of experimental studies to investigate the Meniere disease, there have been little modeling studies, which are helpful to understand the mechanism. Methods: A 3D finite element model of the human cochlea and the middle ear was used for investigation of the relationship between EH and hearing loss at low frequencies and diplacusis (2 specific symptoms of Meniere disease). While the cochlear geometry was simplified as a tapered box shape, the middle ear was based on the real geometry obtained from μCT images. EH is implemented by prestress on the basilar membrane surface in the simulation. Results: The EH did not cause significant hearing loss at low frequencies in both air- and bone-conducted hearing. Rather, this disorder caused a shift in best frequency (BF) position to the base at low frequencies below about 250 Hz. The BF shift can explain the diplacusis because a low-frequency sound can be perceived as a slightly higher frequency so that Meniere patients can perceive 2 different frequency sounds corresponding to a given single-frequency sound. Conclusion: The EH cannot be a sufficient condition for Meniere disease, whereas the hydrops can cause the diplacusis.
