In extremely severe cases, treatments that deaden the inner ear such as gentamicin injections or surgery may be considered. This is a last resort for persons who have severe attacks which are disabling. At present, we favor gentamicin for most instances where destructive treatments are being considered. Injections of gentamicin are given through the ear drum, through a small hole or through a small tube. This procedure allows the doctor to treat one side alone, without affecting the other. Typically, about four injections are given over a period of one month. Some authors have reported improvements in 60 to 90 percent of patients with gentamicin (Driscoll et al., 2009; Bodmer, 2007; Boleas-Aguirre, 2007; Chung, 2007), and Chung reported equally effective results with a single injection compared to multiple injections (Chung, 2007). Dizziness may reoccur one year later, requiring another series. Gentamicin injection can also result in hearing loss (Silvertein 2009; Colletti, 2007).
As of July 2012, a visit to the National Library of Medicine’s search engine, PubMed, revealed 497 research articles concerning AIED disease published since 1964 with eleven of these published in the last year. In spite of this moderate effort by the medical research community, AIED disease remains a chronic, incurable disorder that causes progressive disability to both hearing and balance. At the American Hearing Research Foundation (AHRF) , we have funded basic research on similar disorders in the past , and are interested in funding research on AIED in the future. We are particularly interested in projects that might lead to methods of stopping progression of hearing loss and the disabling attacks of dizziness.

Destructive surgeries are irreversible and involve removing entire functionality of most, if not all, of the affected ear; as of 2013, there was almost no evidence with which to judge whether these surgeries are effective.  The inner ear itself can be surgically removed via labyrinthectomy, although hearing is always completely lost in the affected ear with this operation.  The surgeon can also cut the nerve to the balance portion of the inner ear in a vestibular neurectomy . Hearing is often mostly preserved; however, the surgery involves cutting open into the lining of the brain, and a hospital stay of a few days for monitoring would be required.
