This paper outlines the indications for surgery of congenital ears in complete meatal aplasia and an operative technique used in 35 ears. It is felt that otologic surgery should be done before the pinna reconstruction as it is very important to try and introduce sound into these children at an early age. Most of the patients in this series were 2 to 3 years' old. In addition, the position of the new auricle can be made more satisfactorily around an already established meatus. The value of radiology of the internal as well as the middle ear is stressed and the necessity for providing a stable and uninfected meatus emphasised with regard to the possible fitting of a hearing aid. Failure to achieve a permanent unaided hearing improvement is due to fibrosis at the bottom of the meatus, a problem which is yet to be solved.
本文概述了完全性外耳道闭锁先天性耳部手术的适应证以及用于35只耳朵的手术技术。认为耳部手术应在耳廓重建之前进行,因为尽早让这些儿童听到声音非常重要。该系列中的大多数患者年龄在2至3岁。此外,围绕已形成的外耳道来塑造新耳廓的位置会更令人满意。强调了内耳和中耳放射学检查的价值,以及在可能佩戴助听器方面提供稳定且未感染的外耳道的必要性。未能实现永久性的听力改善是由于外耳道底部的纤维化,这一问题尚待解决。
