Outpatient repair of superior semicircular canal dehiscence via the transmastoid approach.

Objectives/hypothesis: Superior semicircular canal dehiscence (SSCD) syndrome has been a topic of much interest since its first description a decade ago. The symptoms of vertigo, autophony, and Tullio phenomenon have been well described as has the utility of surgical repair. The standard approach described for surgical repair of this problem has been to perform a middle fossa craniotomy followed by plugging of the superior semicircular canal.

Cyberknife radiosurgery for squamous cell carcinoma of vulva after prior pelvic radiation therapy.

Limited options exist for patients experiencing a local recurrence of vulvar malignancies after surgery and pelvic radiation. These recurrences often are associated with cancer-related skin desquamation and poor clinical outcomes. A new radiotherapeutic treatment modality for the previously irradiated patient is cyberknife radiosurgery, which uses a linear accelerator mounted on an industrial robotic arm to allow non-coplanar radiation therapy delivery with sub-millimeter precision.
