当科11年間の耳性脳膿瘍に就いて

　I．緒言

　抗生物質出現以前の時代に於ては，耳性頭蓋内合併症は予後不良であつたが，1935年Domagkのプロントジル発見以来20数年間に於ける抗菌性薬剤の進歩はめざましく，耳鼻咽喉科領域疾患に対しても寄与するところ大なるものがあり，耳性頭蓋内合併症は減少し，手術法の進歩と相俟つて予後は良好となつて来た。私は昭和26年より昭和36年迄の11年間に当科を訪れた耳性脳膿瘍患者につき統計的観察をなし，若干の文献的考察を加えて報告する。

An analysis of 15 cases of otitic cerbral abcess treated at the Otolaryngological Dep-artment of Chiba University Medical School during the period of 11 years from 1951 to 1961 inclusive is made. The majority of patients were males and comparatively young in age ; the cerebral abcess was the result of chole-steatomatous otitis media. A complaint of headache was a common symptom. In rieht-handed indivivisuals left cerebral affection brought on amnesic speech disturbances. But the loss of hearing on the normal side that may be due to hearing center affection was not recognized. The treatment consisted of removal of the irritant and drainage of the abcess which brought favorable results by cure in 65% of cases.
