외상 후 발생한 내이 기종 1예

Pneumolabyrinth is a rare entity in temporal bone fracture. The air in the labyrinthine system is an objective evidence of an abnormal communication between the inner ear and the middle ear or mastoid cavities. We report a case of pneumolabyrinth with temporal bone facture after falling down injury in a 6-years-old boy. It caused severe hearing loss and vertigo, suggestive of destruction of inner ear. Diagnosis was made by means of a high resolution computed tomography (HRCT) scan of temporal bones. This patient was managed conservatively and the pneumolabyrinth was resolved spontaneously. Vertigo was cleared without improvement of hearing loss. (J Clinical Otolaryngol 2008;19:87–91)
