보행장애를 주소로 내원한 21개월 여아의 측두골 골절과 미로진탕

Abstract

Blunt head injury can concuss the membranous labyrinth against the otic capsule. This results in acute hypofunction of some portion of the vestibular neural substrate within the affected labyrinth. Both labyrinthine concussions and transverse temporal bone fractures produce acute unilateral vestibular hypofunction. We describe a 21-months-old child who presented with a ataxic gait for two days. It is difficult to make diagnosis of labyrinthine concussions and temporal bone fractures in children, for we can not know the exact history of trauma and can not perform complete neurologic examination in children. When child present with ataxic gait, the emergency physician should consider labyrinthine concussion and temporal bone fracture in the differential diagnosis and take temporal bone CT.
