A large vestibular aqueduct is one of the commonest radiological abnormalities of the inner ear. A case of acute profound unilateral sensorineural hearing loss and balance disturbance following minor head trauma in the presence of an abnormally enlarged vestibular aqueduct is described. The significance of a diagnosis of large vestibular aqueduct syndrome, in the presence of serviceable hearing, is that it identifies patients who should refrain from activities that increase intracranial pressure to prevent hearing loss.
大前庭导水管是内耳最常见的放射学异常之一。本文描述了一例在存在异常扩大的前庭导水管的情况下，因轻微头部外伤后出现急性重度单侧感音神经性听力损失和平衡障碍的病例。在听力尚可的情况下，诊断大前庭导水管综合征的意义在于，它能识别出那些应避免进行增加颅内压活动以预防听力损失的患者。
