Tullio現象を呈したメニエール氏病3例

抄録

Three cases of Ménière's disease distinctly showing Tullio's reaction are reported.
(1) 47-year-old man whose walk deviates to the right at large sound
(2) 40-year-old man who has the rotating vertigo at large sound
(3) A case of the vertigo fit at the noise of the street-car
Tullio's reaction observed in Ménière's disease can be explained as follows by making reference to the findings with the internal ears of Ménière's disease, which have been made clear since 1938. When the sacculus enlarged by endolymphatic hydrops comes in contact with the inside of the stapes-plate and further the sacculus comes in touch with the utriculus, if either of these is impacted into the semicircular canals, the vestibule and the semicircular canals are stimulated by sound and may cause Tullio's reaction. The author does not deny the idea of the central cause, but it is his point that at least in case of Ménière's disease, it seems better to lay stress upon the periphery and to explain by the endolymphatic hydrops.
The author wishes to make experimental studies of Tullio's reaction with Ménièr's disease in the future.
