摘要 获得性内耳道纤维化是一种离散的临床病理实体，其特征是骨性外耳道中形成纤维组织。在七年的时间里，共对 10 名患者的 12 只耳朵进行了 14 次手术。 4例为外耳炎，2例为化脓性中耳炎并发症，3例为医源性。两名患者的三只耳朵无法查明原因。治疗包括切除所有纤维组织和受累皮肤，进行宽管道成形术、肉成形术，然后通过劈开皮肤移植进行重建。遇到两例运河胆脂瘤。平均两年的随访显示所有患者的听力都有所改善。唯一的并发症是两耳狭窄复发。本文讨论了该病的术语、病因、病理生理学、诊断和治疗原则。
Abstract Acquired medial canal fibrosis is a discrete clinicopathological entity characterized by formation of fibrous tissue in the bony external auditory meatus. Over a seven-year period, a total of 14 operative procedures were performed on 12 ears involving 10 patients. Four cases had followed otitis externa, two were complications of suppurative otitis media, and three cases were iatrogenic. The cause could not be identified in three ears involving two patients. Treatment entails excision of all the fibrous tissue and involved skin, a wide canaloplasty, a meatoplasty, and then reconstruction by split skin graft. Two cases of canal cholesteatoma were encountered. Average follow-up of two years showed hearing improvement in all patients. The only complication was a recurrence of the stenosis in two ears. The paper discusses terminology, aetiology, pathophysiology, diagnosis, and principles of treatment of this condition.
