Abstract
PDF - Labyrinthine fistula refers to a condition caused by an abnormal connection between the inner ear and surrounding structures. Most cases of that occur as a result of a complication brought about by cholesteatoma. It may also be generated by long repeated infections of a mastoid cavity that has been exposed to the outside after canal wall down mastoidectomy (CWDM). The infection is usually repeated for several years or decades after surgery. Therefore, labyrinthine fistula after CWDM is known as a late complication. In this case, labyrinthine fistula occurred in two months after surgery due to postoperative infection. Although cholesteatoma was removed after CWDM and the horizontal semicircular canal (HSCC) was not damaged during the operation, this labyrinthine fistula was thought to develop very early after surgery. Two months after surgery, the patient complained of dizziness, we identified the opened bony labyrinth and damaged endosteum of the HSCC in the patient.

Abstract
PDF
- 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.
