It is well known that head trauma may cause hearing loss, which can be either conductive or sensorineural. Benign paroxysmal positional vertigo and olfactory dysfunction due to head trauma are also well known. The association between sensorineural hearing loss and anosmia, following head trauma, is extremely rare. Two rare cases of post-traumatic occurrence of hearing loss, olfactory dysfunction and benign positional vertigo are reported and the pathophysiology of the association between sensorineural hearing loss, anosmia and benign paroxysmal positional vertigo, after head injury, are briefly discussed. ENT specialists should, in the authors' opinion, be aware of the possible association between anosmia, sensorineural hearing loss and benign paroxysmal positional vertigo after head injury, even in the absence of skull fracture.
众所周知，头部外伤可导致听力损失，其可为传导性或感音神经性。良性阵发性位置性眩晕和外伤性嗅觉功能障碍也广为人知。头部外伤后，感音神经性听力损失和嗅觉丧失之间的关联极为罕见。本文报道了 2 例罕见的创伤后听力损失、嗅觉障碍和良性阵发性位置性眩晕的病例，并简要讨论了头部损伤后感音神经性听力损失、嗅觉丧失和良性阵发性位置性眩晕之间的病理生理学关联。作者认为，耳鼻喉科专家应该意识到即使没有颅骨骨折，头部外伤后也可能存在嗅觉丧失、感音神经性听力损失和良性阵发性位置性眩晕之间的关联。
