レルモワイエ症候群の成立機序に関する臨床的考察

Abstract

The pathogenesis of Lermoyez's syndrome was discussed on the basis of a patient, who was treated by perivascular sympathectomy at the proximal part of the vertebral artery. After this operation “episodic vertigo” disappeared completely, although cyclic fluctuating hearing loss continued as before. The glycerol test performed preand postoperatively was always negative.Therefore, the mechanism of cochlear dysfunction was inexplicable in terms of the blood circulatory disturbance theory or the intralabyrinthine hyper-pressure theory.
