中耳炎診療に對する私見

　諸言

　スルフア剤やペニシリン（以下ス，ペとす）の國産品が普及するにしたがつて，急性中耳炎やその合併症に対する手術例が著しく減少する傾向にある．1947年2月から1948年10月の間に手術をしたムコーズス菌性中耳炎（以下ム中とす）と仮性眞珠腫（以下仮眞とす）に就いて中耳炎診療上の私見を述べ御批判を仰ぐものである．

Kawasaki finds by analysis of cases of otitis media, both, in the acute and chronic, which ultimately required operative treatment, that acute cases are generally caused by "mucosus" infections and the chronic by pseudo-cholestea-tomata.

He believes that a person whose mastoid pro-cess is well developed in air-cells is more vul-nerable to "mucosus" infections ; therefore mak-ing him more prone to attacks of acute mastoi-ditis, which when established, will show involve-ment of cells that might be most deeply and remotely seated. Which conception may explain some cf the cases that advance to mastoiditis that require operative treatments, despite the use of sulfa-drugs and penicillin.

He also believes that, a close relation to be existing between conditions causing pseudo-cholesteatoma and tuberculosis and, calls atten-tion the fact that, tuberculosis is an important factor to be considered when an operation is called for treatment of chronic otitis media.
