両側外転・顔面・聴神経麻痺を生じたCrushing head injuryの1例

A Case of Crushing Head Injury Showing Bilateral Abducens, Facial and Acoustic Nerve Palsies

I．はじめに

　頭部外傷の外力の加わり方には種々の場合があり，極めて複雑である．このうち，contact injuryとacceleration　injuryが特に重要であり，ほとんどすべての症例がこれらに含まれる^3）．しかしながらstatic loading（静力学的荷重）による外傷，すなわちcrushing　head injuryも少なからず存在し，これは頭部外傷の発生機序を論じる上で避けては通れない病態ではあるが，これまで充分な解析はなされていない^{2,7,10,12），}．今回著者らはcrushing head　injuryにて両側の外転・顔面・聴神経麻痺をきたした稀な1例を経験し，その病態および脳神経損傷の発生に関して検討する機会を得たので報告する．

Most head injuries are due to two basic mechanisms, contact or acceleration. On the other hand, static load-ing force makes another type of head injury, so called "crushing head injury". In this report, we discussed the mechanism of the crushing head injury and cranial nerve damage of our case.

A 35-year-old male was admitted to our hospital suf-fering from a crushing head injury. In this accident, his head had been crushed between 1000-kg printing machine and truck bed on both temporal regions slow-ly. He remained fully conscious.
