Abstract
- This study was done on a case of chronic otitis media in both ears of a 47-year-old woman who received tympanization in the left middle ear in a local hospital three years ago. Ossiculoplasty was not tried in this case due to fixation of the stapes. However, conductive hearing loss of the left ear continued after tympanization, necessitating middle ear exploration. After the exposure of middle ear cavity, we found the absence of malleus and incus, and the fixation of stapes. Stapedectomy was carried out and total ossicular replacement prosthesis was also performed for the protection of the oval window by using perichondrium, cartilage and fascia. Postoperative bone conduction showed improvement of 15 dB, and air conduction showed improvement of 22 dB. After the operation, an average air-bone gap was improved within 10 dB. We experienced good hearing improvement without significant complications during the follow up period.
