Abstract

Benign paroxysmal positional vertigo (BPPV) is the most common cause of vertigo of peripheral origin. The lateral semicircular canal (LSCC) follows the posterior semicircular canal (PSCC) as the site of pathology in the majority of patients. Therapy, aiming at relocating particles causing aberrant LSCC stimulation has been applied by forced prolonged positioning, barbecue, and particle repositioning maneuvers. Results of the different techniques are variable. This systematic review/meta-analysis aimed to find out which therapy technique yields higher cure rates. MedLine database provided at National Library of Medicine was searched for randomized controlled trials comparing results of different therapeutic techniques for patients with LSCC BPPV. For studies included in qualitative analysis/synthesis, the following were collected independently by the author: number of participants, count of patients with geotropic and apogeotropic LSCC in each treatment group, and resolution of vertigo/nystagmus assessed by symptomatic improvement and negative supine roll test 1–24 hours following intervention considering the type of LSCC BPPV (geotropic/apogeotropic). Level Ia evidence (systematic review of RCTs) shows superiority of Gufoni maneuver over sham for both geotropic and apogeotropic LSCC BPPV. Comparisons between different therapeutic maneuvers for LSCC BPPV based on results of published RCTs could not be set.
