The three surgical methods currently in use to improve hearing for patients with congenital aural atresia are fenestration of the lateral semicircular canal, canal plasty, and type III tympanoplasty. Because the surgery is difficult and the functional rewards are modest, it should ordinarily be reserved for patients with bilateral atresia. Of the 12 ears operated by the technique of type III tympanoplasty, the average gain in hearing was 22 dB, with seven attaining a 30 dB or better air-conduction threshold. When aural rehabilitative and cosmetic surgery are contemplated, coordinated planning by the surgeons is necessary to acquire the best end result.
目前用于改善先天性耳道闭锁患者听力的三种手术方法是外侧半规管开窗术、耳道成形术和III型鼓室成形术。由于手术难度大且功能改善有限，通常应仅用于双侧闭锁的患者。采用III型鼓室成形术技术进行手术的12只耳朵中，听力平均提高了22分贝，其中7只耳朵的气导阈值达到了30分贝或更好。当考虑进行听觉康复和整形手术时，外科医生需要进行协调规划以获得最佳的最终结果。
