  • Abstract
  • Look Inside

Seven cases with progressive hearing loss were studied clinically, radiologically and electro - otologically. These patients manifested a fluctuat-ing hearing impairment particularly in low fre-quency tones. Canal paresis on the affected side were observed in all cases.

The vertebral angiography demonstrated that the vertebral artery on the affected sides showed a large -diameter and a sharp-angulation at the fourth segment.

These findings seemed to suggest the inner ear lesion due to vertebro-basilar artery insuffiency.
