The injections are performed with the patient lying down and using the office microscope. The ear is first cleaned of wax. A small area of the eardrum is numbed with a drop of medication. A small needle and syringe are then used and the needle is passed through the eardrum at the site that is numbed so that the tip is in the ear, near the round window. This is a membrane where drugs are absorbed in to the cochlea. The fluid is injected in to the middle ear and the patient stays lying down for 20-30 minutes during which he does not swallow or sniff. The drug sits against the round window and is absorbed in to the inner ear. The patient then sits up slowly and leaves the office. Patients should not drive for a few hours after this procedure. Water is kept out of the ear until it is confirmed that the tiny hole has healed.
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.

A total of 16 patients (%) had hearing loss greater than 90 dB with an improvement rate of %; a total of 29 patients (%) had hearing loss of 90 dB or less and greater than to 50 dB with improvement rate of %; a total of 10 patients (%) had hearing loss less than 50 dB and greater than 30 dB with an improvement rate of % (Figure 3 ). Patients with severe losses greater than 90 dB had a poorer recovery (%) compared with losses less than 90 dB (%) ( 𝑃 = 0 . 0 6 Fisher’s test).
