先天性迷路梅毒症例

　Ⅰ．緒言

　1863年Hutchinsonが，先天性梅毒患者に於て難聴と眼疾患，及び歯牙の変型が認められることを見出して以来，梅毒に因る聴器の障碍は，広く耳科領域に於て追求されるようになつた。殊に先天性梅毒による聴器障碍は，その特異な臨床像，即ち上記Hutchinsonの三症候を始め，Hennebertの瘻孔無き瘻孔症状，前庭迷路に於ける所謂paradoxe Erregbarkeit，骨導聴力の異常短縮等の故に多くの症例報告や臨床統計が発表されて今日に至つている。

　私も当科外来に於て数例の先天性迷路梅毒患者を診，これに対して二，三の検索を行うと同時に文献的に些か考察を加えて見たのでこゝに御報告する。

Tsuiki notes the following points in his ob-servation on 10 cases of congenital, labyrin-thine syphilis: The symptoms in this affec-tion generally become prominent during the period of adolescence of the individual: Hut-chinson's symptom triads are readily recog-nized: at times symptoms pointing to abnor-mal stimulation of the vestibular labyrinth may be seen. No clear cut evidence in shor-tening of bone conduction time or presence of Hennevelt syndrome was apparent. Audio-grams taken from these individual failed to reveal a pattern but differed with each indi-vidual, in some bone conduction being better than others. However, the symptom in which these patients suffered in common was the marked loss of hearing.
