The superior canal dehiscence is a disease in which occurs a loss of the bone covering of the upper semicircular canal. If symptoms such as provocable, short-term vertigo attacks when pressing, or hearing loud noises, pulse-synchronized tinnitus and hearing loss occur, then this is also referred to as a superior semicircular canal dehiscence syndrome. These complaints can have the clinical appearance of otosclerosis. We present the case of a 48-year-old woman with hearing loss and vertigo who underwent stapedectomy three times with the aim of improving hearing. After performing the computed tomography and based on the clinical complaints, the diagnosis of superior semicircular canal dehiscence syndrome was confirmed. In summary, it can be said that an alternative underlying diagnosis should be considered if a stapedectomy does not improve the hearing.
