In normal conditions, there are just two inner ear windows: oval and round, both elastically closed; so when there is a superior semicircular canal dehiscence, a "third window" exists in the labyrinth changing the physiology of the inner ear. Objective: to describe superior semicircular canal dehiscence syndrome as a form of presentation of peripheral vestibulopathy. Method: review and discussion of the medical literature. Conclusion: nowadays, there are discrepancies on the real prevalence of this syndrome despite the solution of the diagnostic imaging methods.
