Statistical analysis was made on 1, 632 patients complaining of vertigo or dizziness who visited the Department of Otorhinolaryngology, Fukuoka University Hospital from 1976 to 1980. Among the 15, 850 out-patients, 624 had peripheral vestibular disorders, the rate being 4%. The vertigo or dizziness due to peripheral lesions includes benign paroxysmal positional vertigo (14%), sudden deafness (5.7%), Meniere's disease (5.1%) vestibular neuronitis (2%), etc.The majority of those who had peripheral lesions in the vestibular system suffered from vertiginous attack in March, June and October. In these 13 years in our clinic the number of cases of benign paroxysmal positional vertigo tended to increase, but Meniere's disease has been decreasing.Two cases of paroxysmal positional vertigo without cochlear symptoms (benign paroxysmal positional vertigo and head injury) were investigated by means of the new tilt chair apparatus with reference to the otolithic function. Differential diagnosis of paroxysmal positional vertigo can be made based on our findings.
