聽力恢復を見た聾生徒の耳性化膿性髓膜炎治験例

　岩樣骨蜂窠化膿に因る頭蓋内合併症，特に耳性化膿性髄膜炎は予後不良な疾患であり，最近の化学療法剤の進歩殊にペニシリンの発現以来，其の治癒率は格段の上昇を示しているとは云え，尚危険率の高い疾患である。私は1聾学校生徒の，猩紅熱性慢性化膿性中耳炎に由来する化膿性髄膜炎を，手術による病巣の徹底的清掃とペニシリン使用により治癒せしめ，加うるに化膿性髄膜炎治療の目的で行なつた髄液の大量排除により，予期せざる聽力の恢復を来した1例を経験したので報告する。

　OKU reports a case of an acouired deafness that regained hearing following repeated removal of spinal fluid. A girl, aged 12, with a history of having been affected with scarlet fever at the age 1 year and 4 months that resulted with bilateral chronic otitis media and marked deafness thereafter, is presented suffering from acute left mastoiditis complicated by cerebral involvement. Two operations in a short period of time are performed on the ear. Follow the last operation during a period of 2 weeks a daily spinal puncture is performed. At each of these procedures 30 to 50cc of spinal fluid are removed followed by instillation of 20,000 units of penicillin. However, the removal of the spinal fluid was continued for 30 days. After these treatments, it is revealed that definite improvement of hearing has been established in the nonoperated right ear which had always been deaf. The amount of hearing regained in this ear has not diminished to date, 5 months later.
