title: Superior semicircular canal dehiscence and enlarged vestibular aqueduct.
abstract: Superior semicircular canal dehiscence is a well described labyrinthine defect, detect in pediatric population too. We report a case of superior semicircular canal dehiscence, which radiological diagnosis was confirmed by multiplanar reformatted CT images, associated to omolateral enlarged vestibular aqueduct in a 16-year-old female who presented with congenital hearing loss without vestibular symptoms. Both inner ear malformations act as a third mobile window into the labyrinth and cochleo-vestibular symptoms can result from loud sounds or pressure changes. An early diagnosis should be strived for preserve inner ear functions.
