title: [Dehiscence of the anterior semicircular canal and otosclerosis: a case report].
abstract: The dehiscence of the anterior semicircular canal is a new clinical entity, it is necessary to consider this when a gusher occurs during stapedial surgery.
  
  
  METHODS
  We report a rare case of dehiscence of the anterior canal associated with otosclerosis. This was revealed by a gusher during the initial stapedectomy. At 3 months, an obliteration of the dehiscence was necessary by middle cranial fossa approach (persistant vestibular symptoms), seven months later. Revision stapedial surgery resulted in complete closure of the air-bone-gap.
  
  
  CONCLUSIONS
  High resolution CT scans of the temporal bone are the key to diagnosis. It is necessary to appreciate this pathology with advances in canal and vestibular surgery.
