Superior semicircular canal dehiscence: a new indication for middle fossa craniotomy. Case report.
Superior semicircular canal dehiscence is a recently described condition resulting in pressure-induced vertigo in affected patients. The diagnosis is established with the appearance of characteristic electronystagmographic and neuroimaging findings. This condition is amenable to surgical treatment by resurfacing of the dehiscence in the defect in the middle cranial fossa floor with preservation of superior semicircular canal function. The authors report on the treatment of a 35-year-old man with superior semicircular canal dehiscence by a joint neurosurgical and otolaryngological team.
