唾液腺異物4例

　唾液腺異物は顎下腺に多く耳下腺に少く，其等の導管に多く，腺実質に少いとされて居るが，其等何れの症例も文献に徴するに少い樣である。私は千葉大学医学部耳鼻咽喉科数室に於て唾液腺異物の4例を経験したのでこゝに報告し，本邦文献中に探索し得た22例に就て若干考察したいと思う。

ISHIURA reports 4 cases of obstruction of salivary duct by foreign bodies. 1) Obstruc-tion of stenson,s duct was found in a girl aged 20. After proforming a sialography a hair of a tooth brush the agent of obstruction was expelled through the natural orifice. 2) A girl aged 20 injured the floor of the mouth while eating shrimp from sharp slivers of the crustancea.
