We report an unusual case of contralateral deafness in a 31-year-old man after an uncomplicated blunt force head injury. The patient was presented with a left-sided head injury and complained of profound deafness in his right ear, dysequilibrium, and vertigo. Pure tone audiogram revealed total sensorineural deafness in the right ear. A high-definition computed tomography scan demonstrated no radiological evidence of bony injuries or a fistula. His dysequilibrium had improved 2 months later, but his vertigo and hearing loss persisted. We will discuss several possible mechanisms of injury that may result in deafness after head injury without bony fractures. The literature has been reviewed. Although deafness is not an uncommon complication of head injuries, its presentation in the contralateral ear in the absence of temporal bone fractures following head injury has not been reported before in the medical literature.
我们报告了一例 31 岁男性在无并发症的钝性头部外伤后出现对侧耳聋的不寻常病例。患者表现为左侧头部损伤，并抱怨右侧耳朵听力严重下降、平衡失调和眩晕。纯音听力图显示右侧耳朵全感觉神经性聋。高分辨率计算机断层扫描显示无影像学证据表明有骨损伤或瘘管。他的平衡失调在 2 个月后有所改善，但眩晕和听力损失仍持续存在。我们将讨论几种可能的损伤机制，这些机制可能导致头部外伤后即使没有骨折也会出现耳聋。已对文献进行了回顾。尽管耳聋不是头部外伤的常见并发症，但在头部外伤后无颞骨骨折的情况下出现对侧耳朵耳聋在医学文献中尚未有报道。
