Acquired stenosis of the external ear canal (ASEEC) is a relatively uncommon condition. Stenosis or narrowing of the external ear canal (EEC) occurs lateral to the tympanic membrane resulting in a skin lined blind canal. Recurrent otorrhea, and conductive hearing loss are typical clinical features. Although ASEEC can be due to different etiologies, a common pathogenesis, namely an inflammatory cascade, has been implicated. Clinical evaluation, audiogram, and Computed tomography (CT scan) form the mainstay of diagnosis. Surgery is the primary modality for treatment. Restenosis is the most common postsurgical complication.
获得性外耳道狭窄（ASEEC）是一种相对罕见的病症。外耳道（EEC）的狭窄或缩窄发生在鼓膜外侧，导致形成一个内衬皮肤的盲管。反复耳漏和传导性听力损失是典型的临床特征。尽管ASEEC可能由不同病因引起，但一种共同的发病机制，即炎症级联反应，已被牵涉其中。临床评估、听力图和计算机断层扫描（CT扫描）构成诊断的主要依据。手术是主要的治疗方式。再狭窄是最常见的术后并发症。
