[Treatment approaches to benign paroxysmal positional vertigo. Clinical features in 228 cases of posterior and lateral canalolithiasis].
After having discussed the etiopathogenesis, epidemiology and physiopathology of Benign Paroxysmal Positional Vertigo (BPPV), the authors present their case study covering audiovestibology out-patients treated in the last two years: 228 cases of canalotithiasis-derived BPPV, both posterior (186 cases) and lateral (42 cases). These patients were diagnosed and treated between July 1996 and July 1998 and account for 15% of the 1550 patients complaining of balance and postural disorders seen during that period. Analysis of the results shows BPPV epidemiological data that are practically the same those reported in the literature: greater incidence in females, predominance of posterior canalolithiasis and optimal use of the canalith repositioning techniques. The authors reconfirm the effectiveness of the Semont maneuver and its variations in the treatment of those forms involving the posterior semicircular canal (97% healing). As regards BPPV due to lateral canalolithiasis. The authors feel the vestibular "barbecue" rehabilitation techniques suggested by Lempert--i.e. a 270 degrees rotation starting from the decubitus position on the pathological side, rather than Baloh's traditional 360 degrees rotation--is most suitable for the treatment of BPPV stemming from lateral canalolithiasis. The Lempert technique provided satisfactory results (76% healing) and a reduction in the number of failures (24%).
