  • Abstract
  • Look Inside

We reported six cases of luxation of the stapes. In five cases, the ear drum was perforated at the posterior-superior part. Pure tone audiometry showed moderate mixed hearing loss in all cases. Almost all cases presented with horizontal rotatory nystagmus, and especially rotatory torsional compo-nent was strong. This nystagmus suggested that there was damage to the otolith organs. In almost all cases, surgical closure of the round window was effective for improvement of the vestibular symp-toms.

We suggest that immediate operation should be carried out to prevent exacerbation of symptoms caused by direct trauma.
