特異な経過をたどつた上顎洞異物の一症例

A CASE OF A FOREIGN BODY IN THE MAXILLARY SINUS WITH UNUSUAL COURSE

　耳鼻咽喉科領域における異物のうち副鼻腔異物は，戦時中では小銃，手榴弾の破片などがもつとも多く，平時では誤射，暴発による空気銃弾，転倒時の木や竹，作業中の事故による工具，鼻副鼻腔処置，あるいは歯科治療時のガーゼや診断器具などがみられるが，副鼻腔の解剖学的関係から，その異物は稀な疾患である。

　著者らは原因不明のうちにガラス片が上顎洞に侵入し，しかも長期間なんらの症状もあらわさず無自覚的に経過した興味ある上顎洞異物症例を経験したので報告する。

　A male aged 61 years had complained of nasal discharge with bad odor and sensation of swelling on the right cheek. Caldwell-Luc operation was performed and a foreign body was removed. It was a fragement of glass from a broken speedmeter of a motorcycle.

　The past history revealed that the patient had the motorcycle accident at the age of 50, and he developed a loss of consciousness for about 3 hours after the accident. The patient, however, had no memory of maxillofacial injury at the time of accident. The author assumed from the operative findings that the fragment of glass penetrated the facial wall of the maxillary sinus and stayed there for a considerable length of time without any remarkable symptoms.
