雷管爆破による顎顔面多発骨折症例

A case report：Multiple facial and mandibular fractures by explosion of a detonator of dynamite in attempting suicide

I．はじめに

　本邦では爆発物による自殺未遂例は少なく，生存例も稀である。爆発による顔面の高度の欠損に対して，遊離皮弁以外での再建手段は非常に困難である。今回，自殺企図にてダイナマイト点火用の雷管を口腔内で爆破させ，顎顔面の多発粉砕骨折を生じた1例を経験したので報告する。

We reported a case of multiple facial and mandibular fractures by explosion of a electric detonator of dynamite in a man who attempted suicide. He losed buccal skin and mucosa. Oral mucosa was injured severely. Radiography and computed tomography revealed comminuted fractures of the maxillary and mandibular bones. The deficit of buccal skin decreased due to granulous tissue after one month. The reconstruction of mandibular bone with vascularlized calvarial bone grafting improved misswallowing and enabled for oral intake.
