Abstract:
Benign paroxysmal positional vertigo is the most common disease of the peripheral vestibular disorder. A 51-year-old man showed geotropic horizontal nystagmus in the head roll test. After head-bending posture, the nystagmus of the patient was changed to apogeotropic horizontal nystagmus in the head roll test. We concluded that transition of canalolithiasis into cupulolithiasis happened during head-bending posture. The cupulolithiasis was returned to canalolithiasis by using side-lying position with the affected ear downward for approximately 45 minutes.
