Abstract
OBJECTIVE: To investigate the incidence of benign paroxysmal positional vertigo(BPPV) and to further understand the possible mechanism of BPPV. METHODS: To observe the incidence of BPPV among vestibular neuritis, sudden deafness, Meniere's disease and Bell's palsy at vertigo clinic from January at 2004 to November at 2006 and to compare the therapeutic results with that of the primary BPPV. RESULTS: There are 4 types of inner ear disorders involved in the concomitant BPPV, ie, vestibular neuritis, sudden deafness, Meniere's disease and Bell's palsy and the incidence are 9.5% (5/53), 38.9% (35/90) and 0.3% (1/381) respectively; and there was 1 case of BPPV concomitant to Bell's palsy. Among the 42 concomitant BPPV, 5 cases were horizontal canal BPPV, 37 cases were posterior canal BPPV, and 1 cases had complicated anterior BPPV during repositioning maneuver. 39 cases of concomitant BPPV were canalithiasis and 3 cases were cupuliothiathitis, of which 75% (27/36) of concomitant BPPV emerged within 1/2 years after the onset of primary inner ear disorders. The therapeutic efficacy of the concomitant BPPV with canalith repositioning was similar to that of the primary type of BPPV. CONCLUSIONS: Following some inner ear disorder, BPPV could emerge, such as sudden deafness, vestibular neuritis and Meniere's disease. The most common type of BPPV was canalithiasis of posterior canal, and the cupulolithiasis of horizontal canal was uncommon. The anterior canal therapeutic efficacy of the concomitant BPPV with canalith repositioning was similar to that of the primary type of BPPV. The therapeutic efficacy of the concomitant BPPV with canalith repositioning was similar to that of the primary type of BPPV.
