BENIGN PAROXYSMAL POSITIONAL VERTIGO: PRESENT PERSPECTIVE

Abstract

Objective of this article was to review the current concepts regarding etio-pathogenesis and natural history of benign paroxysmal positional vertigo (BPPV), various diagnostic and therapeutic procedures in use for its different variants and rate of its recurrence after treatment. Representative articles were selected and reviewed. Idiopathic canalolithiasis of posterior semicircular canal is the commonest pathology. Making correct diagnosis of different clinical variants is at times challenging. Once diagnosed most of these conditions respond well to simple office based particle repositioning maneuvers (PRM). BPPV can spontaneously abate in some cases. Recurrence with secondary types of BPPV is more than with that of idiopathic variety. Awareness and recognition of this condition is very important as vertigo is often treated by different specialties in Nepal.
