Based on data from 109 patients operated upon for 125 major aplasias of ear, clinical and operative aspects and results of surgery are analysed. Functional prognosis is related essentially to the nature of the stapes, normal in 66% of cases, and the quality of healing of the newly formed canal. One auditive result out of four in cases of unilateral aplasia and one out of two in bilateral cases constituted the proportion of patients obtaining socially valuable postoperative auditive gain. Functional surgery for aplasia of ear should therefore be reserved mainly for bilateral forms because of the lack of any alternative to apparatus wearing.
基于109例接受125处耳部主要发育不全手术患者的数据，对手术的临床和操作方面以及手术结果进行了分析。功能预后主要与镫骨的性质有关，66%的病例镫骨正常，还与新形成耳道的愈合质量有关。单侧发育不全病例中四分之一的听觉结果以及双侧病例中二分之一的听觉结果构成了术后获得具有社会价值听觉改善的患者比例。因此，由于佩戴助听器没有其他选择，耳部发育不全的功能性手术应主要保留给双侧病例。
