Multiple-canals Benign Paroxysmal Positional Vertigo - A Single Case Study

Vast number of individuals with BPPV frequently visit Primary health centers, Otorhinolaryngology and Neurology clinical centers. Amongst vestibular disorders, Benign Paroxysmal Positional Vertigo (BPPV) is the most common and non-life threatening vertigo (1). Multiple-canals BPPV has been particularly examined, as the chief basis of various atypical forms of disease. This case report presents a type of nystagmus evoked during the investigative maneuvers of BPPV. A 66 years old male with a complaint of vertigo was subjected to vestibular assessment. During the assessment, strong beating geotropic horizontal nystagmus on right side in conjunction with up beating tortional component of posterior canal origin was observed thereby, labeling the individual with multiple Semicircular canal (SCC) BPPV. Barbeque 360� Maneuver and Semont�s maneuver were performed for canalith repositioning of two involved SCCs on the right side. This mixed component of nystagmus, if not observed carefully during assessment can lead to wrong diagnosis of the patient. Therefore, it is essential to carefully observe the nystagmus changes during the assessment to perform accurate canalith repositioning.
