Horizontal canal benign paroxysmal positional vertigo in a fighter pilot

Abstract

ABSTRACTBenign paroxysmal positional vertigo (BPPV) is the most common disorder of the peripheral vestibular system, characterized by intense, positional provoked vertigo. BPPV is thought to occur due to canalithiasis of the posterior semicircular canal. Recently, a new entity of BPPV, known as horizontal canal (HC)-BPPV, has been recognized. Although only 3 to 8% of BPPV is due to horizontal canal involvement, HC-BPPV is not rare. We present a case of a naval fi ghter pilot who had an incident of HC-BPPV on the ground. The pilot aeromedical evaluation and considerations are discussed.
