Gunshot injuries in the periauricular region can result in massive tissue distortion and destruction. The soft tissue effects can be so dramatic that otologic abnormalities can be initially overlooked, especially by non-otolaryngologists. Delayed stenosis or complete closure of the external auditory canal can occur. We present two cases of post-traumatic ear canal atresia that were initially overlooked by non-otolaryngologists, until secondary plastic reconstructive operations were performed in which preauricular skin incisions entered into large canal cholesteatomas. These canal cholesteatomas resulted from total obstruction of the external auditory canal after trauma.
耳周区域的枪伤可导致大量组织变形和破坏。软组织损伤可能非常严重，以至于耳部异常最初可能被忽视，尤其是非耳鼻喉科医生。外耳道可能会出现延迟性狭窄或完全闭锁。我们报告两例创伤后耳道闭锁病例，最初非耳鼻喉科医生未发现，直到进行二期整形重建手术时，耳前皮肤切口进入大的耳道胆脂瘤才被发现。这些耳道胆脂瘤是外伤后外耳道完全阻塞所致。
