Abstract

|
The purpose of this study was to investigate cases in which the number of treatments for benign paroxysmal positional vertigo increased due to changes in the semicircular canal inflow of the otolith. Video Nystagmus testing was conducted on 1,450 patients who visited Suncheon S Hospital in Jeollanam-do, South Korea. 496 patients were treated from May 2018 to December 2019. A survey was conducted on 31 patients whose semicircular canal inflow area was abnormal. The number of these patients that had three or more canalith repositioning maneuver treatments was 42.8%, which is much higher than the 8.5% for other patients with benign paroxysmal positional vertigo. The prognosis factors that increase the number of treatments requiring the canalith repositioning maneuver include idiopathic conditions, cerebral infarction, trauma, migraine, tinnitus, vestibulopathy, cerebral infarction, and cerebrovascular diseases. Therefore, patients who have had an increased number of treatments of the canalith repositioning maneuver should have a follow-up examination for the prognosis factors that can frequently cause otolithiasis. Even if dizziness improves after the canalith repositioning maneuver it is still prudent to do simultaneous prognosis factor treatment.
