定义
获得性外耳道狭窄被描述为由多种不同原因引起。从那时起，对该病组织学和影像学研究表明，由这些不同原因引起的一系列炎症改变是导致内耳道纤维化的主要发病机制。一旦外耳道完全阻塞，手术是主要治疗方法。
Acquired stenosis of external auditory canal was described as resulting from a number of different causes. Since then, histology and imaging studies of this disease have shown that a common cascade of inflammatory changes resulting from these different causes is the primary pathogenesis leading to medial canal fibrosis. Once there is complete obstruction of the external auditory canal, surgery is the primary treatment.
