Abstract
Sixty eight cases of benign paroxysmal positional vertigo (BPPV) were studied.
Sexual differences were observed on female predominancy.
The most predominant age of the patients was the fifth decade, followed by the fourth, third and sixth decade.
Vertiginous a ttacks appeared frequently in Feb., Mar., Jun., Nov., and Dec.
Hypertension, head & neck injury, heart disease were significant causative factors.
Vertigo disappeared within the first month in 53% of the cases, but recurred in 18% of the cases. Positional nystagmus was observed in 54% of the cases, positioning nystagmus in 75% of the cases. In 12 cases, unilateral caloric reponses were reduced.
We recommend the established otolith function test in the stu d y of causative factors and clinical condition.
