発熱に伴った反復性難聴の1例

A Case of Recurrent Hearing Loss Induced by Fever

I．はじめに

　一般に，感音難聴は突発性難聴の新鮮例以外には聴力は不変か進行性に増悪するものが多い。しかしながら，ごく一部には比較的短期間に聴力の悪化，改善を反復するものもある。最近，われわれは発熱とともに変動する両側感音難聴の興味ある1例を経験したので報告するとともに，従来の報告例と比較し若干の考察を加えた。

　A 22-year-old woman has developed recurrent bilateral hearing loss without vertigo whenever she had suffered from fever since her childhood. Hearing loss was occurred with fever due to not only infectious diseases of the upper respiratory tract, but the unknown etiology, however, the severity of the hearing loss depended on the degree of fever. She showed no apparent abnormalities upon clinical examinations of the immunological, hormonal, metabolic Functions and of the autonomic nervous system.
