両耳聾となった小児頭部外傷の1例

Bilateral Complete Deafness following Head Injury in a Child

I．はじめに

　頭部外傷による聴覚障害はしばしばみられるが，完全聾となることは稀である．われわれは頭部外傷後に聴覚以外の神経症状および知能，精神機能は正常に回復して，両耳完全聾となった症例を経験し，現在も経過観察中である．このような症例の報告はいまだみられず，極めて稀な症例と思われる．考察を加えて報告する．

A case of head injury is reported because it presented such an unusual symptom as sudden, bilateral com-plete deafness.

An 11-year-old boy was involved in a traffic accident while riding on a bicycle. He was admitted immediate-ly after the accident in semicomatose state. The pupils were isocoric and pupillary light reflex was normal. Conjugate deviation to the right was seen. Oculo-cephalic response was absent. X-rays of his skull showed two linear fractures in the occipital bone.
