- Background
and Objectives:The purpose of this study was to investigate the characteristics of gentamicin-induced vestibulotoxicity of otolith organs and preventive effect of low power laser to vestibulotoxicity by assessing the result of earth vertical and the off vertical axis rotation tests.
Materials and Method: Twenty guinea pigs were grouped into two groups, laser and no laser group. Vestibulotoxicity was induced by intratympanic injection of gentamicin. Prevention of the vestibulotoxicity was studied by irradiation of low power laser. Off vertical axis rotation tilted 30 degree relative to the earth vertical axis was applied to evaluate the otolithic function.
Results
Gentamicin induced vestibulotoxicity was confirmed by gain decreasing in slow harmonic acceleration test and modulation decreasing in the off vertical axis rotation test. Prevention effect of low power laser to gentamicin induced vestibulotoxicity was confirmed by modulation maintaining in the off vertical axis rotation test and gain maintaining in the earth vertical axis rotation.

Abstract

- Canalith repositioning maneuver is effective to treat benign paroxysmal positional vertigo(BPPV). This case showed
complicated form of the BPPV such as changes of canalolithiasis to cupulolithiasis, involvement of one canal to two
canals and from unilateral to bilateral involvement during the reposition maneuver.
This patient was diagnosed as left lateral canalolithiasis at first. After left barbecue maneuver, the type was changed
to the right posterior cupulolithiasis. Semont maneuver was performed and then the type of BPPV was changed to
combined type with right posterior canalolithiasis and left lateral canalolithiasis. We performed left barbecue maneuver
and right Epley maneuver. Then the type of BPPV was changed to left lateral cupulolithiasis. After Brandt-Daroff
maneuver and left barbecue maneuver, nystagmus and dizziness disappeared finally.
