自傷行為による頸部切創の9症例

Nine Cases of Neck Injury by Suicide Attempt

I．はじめに

　頸部には頸動静脈，喉頭，気管，食道，脊髄などの重要臓器があり，頸部切創は致死的となる可能性が高い。われわれ耳鼻咽喉科・頭頸部外科医は頸部の外傷を扱う科として，救急救命の現場で果たす役割は大きい。頸部切創の原因には交通事故，労働災害，スポーツ事故などがある。近年，不景気な社会に伴い，自殺企図などの自傷行為による頸部外傷で，救命救急に搬送される患者が増加している^1）。当科では最近1年間に自殺企図による頸部切創を9例経験したので，若干の文献的考察を加えて報告する。

　Nine cases of the neck injury due to suicide attempt were reported. Two cases had the history of schizophrenia and 4 cases had depressive disorder. They were all surgically treated and did not have any functional disorders postoperatively.

　All patients were clinically followed by psychiatrist and otolaryngologist postoperatively.

　Neck wound due to suicide attempt tends to be critical because of the airway damages and major vessel injuries. We presented 2 case histories of severe neck injuries. We emphasize the significance of psychiatrist's involvement in treatment after patient's discharge to prevent the recurrence of the suicide attempts.
