گزارش يازده مورد ترميم جراحي آترزي مادرزادي جراحي گوش خارجي

Background and Objectives: Congenital aural atresia (CAA) occurs in 1 per 10000 to 20000 live - births and leads to conductive hearing loss. CAA can be associated with inner ear abnormalities. Management of unilateral CAA is controversial. Various surgical approaches, timing of repair, associated microtia, and variable hearing results play a role in this controversy. Materials and Methods: There were 11 cases with CAA who underwent correcive surgeries. Preoperative and postoperative hearing levels, associatied microtia, pneumatization of mastoid air cells, course of facial nerve, ossicular chain position, surgical approach, method of ossicular reconstruction, complications, sex and age distribution were evaluated among these 11 cases. Results: Hearing improvements were excellent in 8 out of 11 cases in which postoperative speech reception threshold (SRT) was 30 dB or less. Conclusion: Repair of CAA can be done successfully in patients older than 4 years of age with pneumatized temporal bone and significant conductive hearing loss.
