A 41-year-old man presented after forceful penetrating ear injury. He had incapacitating vestibular symptoms. Computed tomography revealed pneumolabyrinth with a fractured stapes that was >90 degrees rotated and subluxed into the vestibule, such that the crura and capitulum could be seen in the vestibule. Surgical repair reversed the vestibular symptoms, but there was persistent hearing loss. Stapes fractures are unusual and rarely associated with subluxation into the vestibule. When this does occur, there is usually simple footplate depression. This case demonstrates a rare stapes fracture with pneumolabyrinth and >90 degrees stapes rotation, then subluxation into the vestibule. Laryngoscope, 2009.
一名41岁男性在耳部遭受强力穿透伤后前来就诊。他有严重的前庭症状。计算机断层扫描显示内耳积气，镫骨骨折，旋转超过90度并半脱位进入前庭，以至于在前庭中可以看到镫骨脚和小头。手术修复改善了前庭症状，但听力损失持续存在。镫骨骨折并不常见，很少与半脱位进入前庭相关。当这种情况确实发生时，通常是单纯的镫骨底板凹陷。本病例展示了一种罕见的伴有内耳积气和镫骨旋转超过90度、随后半脱位进入前庭的镫骨骨折。《喉镜》，2009年。
