A 24-year-old man sustained significant injuries as a result of a motor bicycle accident. CT scans demonstrated multiple intracranial injuries including bilateral temporal bone fractures. On emergence from sedation, the patient reported right-sided hearing loss which was attributed to ossicular chain disruption after the incus was found to be in the external auditory canal. Unexpectedly, the initial conductive hearing loss resolved with conservative management and an ossicular chain reconstruction was not required. This is an unusual case of impressive long-term good hearing outcomes following complete dislocation of the incus and extrusion from the middle ear.
一名24岁男子因摩托车事故受重伤。CT扫描显示多处颅内损伤，包括双侧颞骨骨折。患者从镇静状态苏醒后，报告右侧听力丧失，这归因于砧骨位于外耳道后听骨链中断。出乎意料的是，最初的传导性听力损失通过保守治疗得到解决，无需进行听骨链重建。这是一例砧骨完全脱位并从中耳挤出后长期听力结果良好的罕见病例。
