Abstract
Abstract: Barany Society includes bilateral typical posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV) in its classification of multicanal subtype. In the past decade, less-common and atypical subtypes of PSC-BPPV, like short-arm and non-ampullary arm posterior semicircular canalolithiasis, have emerged, requiring the conduct of conventional and auxiliary positional tests on both sides to uncover their bilaterality. Authors hereby report three atypical less-common subtypes of bilateral PSC-BPPV, discussing their clinicodemographic profiles, management by repositioning maneuvers and physical therapy, and follow up. Both Case 2 and Case 3 are precisely tri-canalolithiasis (bilateral ampullary arm posterior semicircular canalolithiasis with co-occurring right non-ampullary arm posterior semicircular canalolithiasis in Case 2 and bilateral short arm with co-occurring left ampullary arm posterior semicircular canalolithiasis in Case 3), which has not been reported previously in the literature. There has been only one previously reported case of bilateral non-ampullary arm semicircular canalolithiasis, and it is now observed in Case 1.
期刊介绍:
The journal has a clinical foundation and has been utilized most by clinical neurologists for improving the practice of neurology. While the focus is on neurology in India, the journal publishes manuscripts of high value from all parts of the world. Journal publishes reviews of various types, original articles, short communications, interesting images and case reports. The journal respects the scientific submission of its authors and believes in following an expeditious double-blind peer review process and endeavors to complete the review process within scheduled time frame. A significant effort from the author and the journal perhaps enables to strike an equilibrium to meet the professional expectations of the peers in the world of scientific publication. AIAN believes in safeguarding the privacy rights of human subjects. In order to comply with it, the journal instructs all authors when uploading the manuscript to also add the ethical clearance (human/animals)/ informed consent of subject in the manuscript. This applies to the study/case report that involves animal/human subjects/human specimens e.g. extracted tooth part/soft tissue for biopsy/in vitro analysis.
