Abstract

In this article we presented the results obtained in functional and cosmetic surgery for congenital aural atresia (CAA) along with literature data and discussed the factors important in the success of the surgical treatment. A total of 544 cases (599 ears) of CAA including 489 unilateral and 60 bilateral atresia were treated in the last 30 years. The ratio among males and females was 2/1 with frequency in males. The age of patient treated ranged from 5 to 38 years old. All the patients had a clinic, audiologic and radiologic evaluation before the surgery. The technique of the surgery applied to the patients was transatresic approach. Our cases 30% of were syndromic (181 hemifacial microsomia, 3 Treacher Collins, 4 Goldenhaar) and the other 70% was nonsyndromic. The preoperative audiologic evaluation of the air-bone gap was found to be 50-60 dB. In the functional outcomes increasing airbon gap were: 40 dB in 10%, 30 dB in 40% and 20 dB in 40% of patients. Remaining 10% patients did not have gain. There were no labirynt injury in any patients and no need of hearing aids. Modest hearing gain could be achieved. Transient facial paralysis was developed in 5 patients and none became permanent. The lateralization of the tympanic membrane was the most common late complication. The most important problem in cosmetic surgery was keloid and scar formation. Free skin graft and enlargement of the canal 1.5-2 times from that required were used to prevent the restenosis of the new canal.
