ABSTRACT

Background: Since its first descriptions, the superior canal dehiscence syndrome has been recognized as a rare cause of both vestibular and hearing long lasting symptoms. Its origin is related to a distinctive anatomic defect in the temporal bone and has been linked to congenital and degenerative causes, so far without being determined the main cause. Due to its unspecific symptoms, the accurate prevalence in the general population is unknown; however, some series have reported incidences from 0.5% to 10% and in bilateral cases the prevalence is more difficult to determine.
Clinic case: A 43-year-old female patient, with imaging evidence of the temporal bone defect.
Conclusions: Despite being a relatively rare condition, more and more fundamental aspects of the behavior of superior canal dehiscence are becoming known; it is one of the best known vestibular disorders within its pathophysiology.
