Further Outpatient Care

Patients are monitored based on the intervention and the severity and complexity of the patient's symptoms. Patients who undergo a craniotomy for repair should expect to stay in the hospital for 1-7 days (median 2 d). They may experience imbalance for approximately one month postoperatively.



The success rate in the treatment of superior canal dehiscence is quite high. In 2005, a study looked at 20 patients with severe symptoms who underwent surgical repair of their superior canal dehiscence through a middle fossa approach. [15] Canal plugging was performed in 9 patients and a resurfacing technique was performed in 11 patients.

Complete resolution of all vestibular symptoms and signs was achieved in 8 of the 9 patients after the canal was plugged. A lower but still significant number of patients with a resurfacing procedure (7 of the 11) had resolution of their vestibular complaints. A total of 15 of the 20 patients (75%) of the patients had resolution of their symptoms after surgical plugging or resurfacing of their dehiscent canal.
