superior semicircular canal dehiscence / superior canal dehiscence syndrome - known as Minor syndrome, superior canal dehiscence is a middle fossa skull base defect involving one of the vestibular (balance) organs. Specifically, a tiny hole in the superior (also known as anterior semicircular canal) in one or both ears can cause hearing loss AND/OR imbalance / dizziness, fullness of the involved ear and autophony (echo during self-vocalization). Superior semicircular canal dehiscence (SSCD) or superior canal dehiscence syndrome (SCDS) can result in many symptoms that resemble more common disorders of hearing loss and imbalance like otosclerosis, Eustachian tube dysfunction, patulous Eustachian tube, Menieres disease or BPPV.

Managing an acute attack involves preparation. This includes consulting with a physician about any appropriate drugs that can be taken when an acute attack occurs, and deciding ahead of time when it is appropriate to go to a hospital. During an attack, it is helpful to lie down in a safe place with a firm surface, and avoid any head movement. Sometimes keeping the eyes open and fixed on a stationary object about 18 inches away is helpful. In order to control dehydration, a doctor should be called if fluid intake is not possible over time due to persistent vomiting.

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.

Some reports maintain that a cold or other upper respiratory illness preceded the onset of SSNHL in as many as 40 percent of cases. Unfortunately, these reports lack corresponding data on the comparative frequency of upper respiratory illness in a matched control population. What about the evidence of blood examinations? In response to a virus, the immune system produces a temporary increase in the level of antibodies against the specific virus, and many case reports on patients with SSNHL show that they experience a brief, sharp rise in antibody levels against common viruses such as herpes, flu, mumps, or rubella.
