Abstract
A school-girl, eighteen years old, was attacked by tinnitus, hearing disturbance on the left side and vertigo in August, 1966.
On the 12th of October of the same year she was attacked again by vertigo and nausea. When she visited the ENT clinic of Kochi Prefectural Central Hospital, it was discovered by audiometry that she had a perceptive deafness in the left ear. It was discovered through ENG that she had positional nystagmus to the left with the eye closed. Left CP was also proved to be in her.
About two years from that time she suffered from the occasional attacks of vertigo. During this period she was examined repeatedly with the audiometer. Her audiogram showed no change at all. But at the 4th of December, 1968, her audiogram recuperated to the normal range.
