Congenital aural atresia (CAA) is a common anomaly in the area of otolaryngology. It requires an early assessment of hearing and a determination of the degree of the atresia. Surgical management of congenital aural atresia is required for hearing gain and appropriate auditory canal status for hearing aid. The authors analyzed the preoperative otologic findings, surgical findings, postoperative complications and postoperative hearing results of twenty-five ears in twenty-one patients with congenital aural atresia which were surgically corrected by anterior approach (except in one case) from Jan. 1987 to Feb. 1992. Audiologic follow-up ranged from two months to four years (N=21). Twenty-five primary and eight revision operation in eight patients were performed. The final hearing result was 34 dB in air-bone gap (averaged for 500, 1000, and 2000 Hz) in comparision with preoperative air-bone gap, 53 dB (N=21). The final air conduction was an improvement of at least 40 dB (serviceable hearing) in 71% of patients. Meatal stenosis was the most common postoperative complication and occurred in twelve patients in primary operations were (N=25). There were no instances of facial nerve palsy or sensorineural hearing loss. There were no specific differences in the hearing results according to type of congenital aural atresia and tympanoplasty type.
