突発性難聴と診断された反復性聴覚障害の4症例

抄録

It is assumed that no relapsing hearing loss occurs in sudden deafness. The author has reported 4 cases of relapsing hearing loss first diagnosed as sudden deafness. An arachnoid cyst in cerebellar pontine angle was found in one case. A medially situated high jugular bulb was confirmed in one case. Immunological disorder was found in one case. No distinct cause was determined in one case. To exclude various clear-cut causes, investigation and follow-up (time and course) should be performed in patients with sudden deafness.
