頬部に刺入し外耳道および耳後部より摘出された異物症例—本邦最近27年間における外傷による耳異物症例について

FOREIGN BODY OF THE CHEEK RESULTING IN REMOVAL OF MULTIPLE PIECES FROM THE EXTERNAL EAR CANAL AND POST AURICULAR REGION

　I．はじめに

　耳鼻咽喉科領域における異物としては外耳道異物がもつとも多いとされ，決して珍しいものではないが，外傷によつて惹き起こされた外耳道異物は比較的稀なものである。

　最近，われおれは頬部に刺入した竹片が外耳道，耳後部より，約7カ月間を要してようやく完全に摘出された症例を経験したので報告し，あわせて本邦における27年間の外傷による外耳道異物症例について若干の検討を行なつた。

　A boy, aged 2, while riding a tricycle accidently fell on a bamboo stick. Two days following this accident the patient developed a trismus. Eight pieces of bamboo slivers were removed from the wounded area after which the latter healed uneventfully. However, about 1 month after the injury the left ear was found to be involved with otitis media that continuously discharged for 51 days and finally turning into growths of granulation tissues. With the removal of granulations a bamboo sliver was, also, removed from this area. And, thereafter, for the ensuing period of 7 months, 25 pieces of bamboo slivers were removed from the same ear. The patient recovered.
