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.
