Abstract:
The superior canal dehiscence syndrome (SCDS) is a rare disorder caused by the dehiscence of the temporal bone overlying the superior semicircular canal. It has become apparent that SCDS can lead to a variety of clinical manifestations, vestibular and/or auditory, in contrast to the typical symptoms, as initially described. We recently examined a 54-year-old woman with unilateral stepsynchronous tinnitus without any vestibular symptoms. Tinnitus is a quite unremarkable finding among variable symptoms of the syndrome; however, it can be one of the clues to identify SCDS when it is accompanied by low-frequency conductive hearing loss. Therefore, in diagnosing SCDS, attention must be also paid to those patients with nonspecific complaints, for example, stepsynchronous tinnitus.
