In the last 20 years 89 middle ear operations were performed on 71 patients with unilateral or bilateral microtia (grade II or III). The methods and the results are described and discussed. In 79.5% we produced a wide auditory canal and achieved an overall hearing gain of 17 dB. We usually do not carry out middle ear surgery in unilateral atresia. In bilateral atresia the child is fitted with a bone conduction hearing aid as soon as possible and is operated on at the age of 4 or 5 years. After middle ear surgery we reconstruct the auricle at an age of 5 or 6 years. If necessary these children are then fitted with an air conduction hearing aid.
在过去20年里，对71例单侧或双侧小耳畸形（Ⅱ级或Ⅲ级）患者进行了89例中耳手术。对手术方法及结果进行了描述和讨论。79.5%的患者形成了宽大的耳道，听力总体提高了17分贝。对于单侧闭锁，我们通常不进行中耳手术。对于双侧闭锁，患儿尽快佩戴骨传导助听器，并在4或5岁时进行手术。中耳手术后，在5或6岁时进行耳廓再造。如有必要，这些患儿随后佩戴气传导助听器。
