We report a retrospective study of 57 cases of minor aplasia of the ear. Each case was analyzed according to the clinical presentation, audiometric results and preoperative radiography. Intra-operative classification of the malformation was obtained in 56 of the 57 cases. The post-operative anatomic and functional results were analyzed. Stapedectomy in type II malformations (stapedo-vestibular ankylosis) gave the best results but this procedure also carries the highest risk for the inner ear. Globally, functional results were good or average in 48% of the patients. These results may appear unsatisfactory but must be appreciated in light of the fact that half of the patients benefited from the operation (particularly in eliminating further use of an external hearing aid). Nevertheless, the long-term stability of these audition results is unknown.
我们报告了一项对57例耳部轻度发育不全病例的回顾性研究。根据临床表现、听力测试结果和术前影像学检查对每个病例进行分析。57例中的56例获得了术中畸形分类。分析了术后的解剖学和功能结果。II型畸形（镫骨-前庭关节强直）行镫骨切除术效果最佳，但该手术对内耳的风险也最高。总体而言，48%的患者功能结果良好或一般。这些结果可能看起来不尽人意，但鉴于一半的患者从手术中获益（特别是不再需要使用外部助听器），必须对此加以认识。然而，这些听力结果的长期稳定性尚不清楚。
