脳性小児麻痺児童の聴力障害に関する研究（第一報）

HEARING DISTURBANCES AMONG CHILDREN AFFECTED WITH POLIOMYENCEPHALITIS

　Ⅰ．緒言

　脳性小児麻痺（C. P.）患者は四肢の運動機能障害，神経系統疾患にしばしば聴力障害を随伴していることは，旧来より，Johnsen^1）（1951），Gerrard^2）（1952）田口^3）（1959），今西^4），他（1963）らによつて報告されている。

　およそ，本障害はたんに人間相互の意思疎通を妨害するに止まらず，社会的共同生活をおびやかすものとしての重要性は四肢の運動機能障害に比し優るとも劣らない注意を要する。にもかかわらず，脳性小児麻痺の研究上，聴力に関する問題は未開拓の分野を多く残し，等閑に附せられがちである。

　Hearing test were made upon 65 children institutionalized at the Osaka Seshi Gakuin for after care in poliomyencephalitis.

　Deafness was found in 18 children, 33 ears, or 27.6%. In 15 individuals the deafness was bilateral involvement, 23%; in 3 children it was unilateral.

　Hearing loss among the children affected with poliomyencephalitis was definitely higher in rate than other normal children who were not so affected. The hearing test was based upon the standard adopted by the Ministry of Education.

　The loss of hearing was larger as the lesion present was more complicated which ranged from spastic type to athetotic to spastic-athetotic; the involvements were respectively, 24.1%, 37.5% and 37.5%.
