初回発作から観察し得たメニエール病34症例について

抄録

Many studies have been performed on cases with chronic Ménière's disease who have had recurrent previous attacks. The purpose of the present study was to investigate the vestibular and cochlear manifestations of incipient Ménière's disease. None of the patients in this study had had a single attack until the current hospitalization, thereafter, they had recurring episodes of vertigo and hearing loss. The following results were obtained: 1. Meniere's disease is most often seen in the fifth decade of life. However, in my investigation, 91% of the 34 cases occurred before 48 years of age, and the most incidental age at onset was at 35 years of age. 2. At onset and at the second attack, a marked fluctuation in the lower frequencies was noted when compared with the third attack. 3. The vertigo score was 3.1 at the second attack, 2.4 at the third attack, and 2.2 at the fourth attack. The interval between the third and fourth attack was longer than the previous attack intervals.
