Abstract

The superior canal dehiscence syndrome is an uncommon anatomical lesion characterized by loss of the bone covering the superior canal, so that there is a potential communication between the canal and the craneal cavity. This defect can be diagnosed by an image test, usually the Computed Tomography. Due to this pathology patients go to the otoneurologist referring a conductive hearing loss with normal middle ear function and normal stapedius reflex threshold or vertigo induced either by loud noises or middle ear pressure changes such as Valsalva manoeuvres.In this paper we present two cases which explain each clinical form.
