ABSTRACT

OBJECTIVE To observe the clinical characteristics and curative effect inpatients with benign paroxysmal positional vertigo(BPPV). METHODS The data of 1000 BPPV patients were retrospectively analyzed. RESULTS 1. There was no significant difference in age between men and women; There was significant difference in incidence between men and women; 2. The single semicircular canal was involved in 993 cases, 2 semicircular canals were involved in 7 cases, canalolithiasis in 818 cases, cupulolithiasis in 175 cases; 3. The posterior semicircular canalwas involved in 587 cases, horizontal semicircular canal in 402 cases, anterior semicircular canal in four cases. The incidence of the right side was significantly higher than that of the left side; 4. The average treatment times of canalolithiasis and cupulolithiasiswere statistically different; 5. BPPV canalolithiasis and cupulolithiasisonetimerepositi on cure rate is 62.5％ and 42.3％ respectively; 6. There was no correlation between nystagmus velocity,affected sideand reposition times in horizontal BPPV. CONCLUSION BPPV has the following characteristicscs. First of all, popularin the middle-aged, elderly population and more common in women, single semicircular canal involve predominantly. Second, most of BPPV involve posterior semicircular canal, horizontal semicircular canal lesion take the second place and anterior semicircular canal lesion was least. Most of BPPV occur in the right side andiscanalolithias type. Thirdly, the average treatment times of BPPV of cupulolithiasis type is more than that of canalolithiasistype.
