[Combined therapy with surgery and stereotactic radiosurgery for facial schwannoma: case report].
The authors report the successful case of combined therapy using surgery and stereotactic radiosurgery for facial schwannoma in the middle cranial fossa, and discuss the surgical strategy for preservation of facial nerve function. This 27-year-old man presented with a 9-year history of right facial palsy and spasm. CT scan and MR imaging demonstrated a tumor 3 x 3 x 4 cm in size extending to the intradural middle cranial fossa from the petrous bone. After total removal of the intradural tumor, gamma knife radiosurgery was performed for residual tumor in the petrous bone. The marginal dose to the tumor was 12 Gy. Facial spasm disappeared, but facial palsy is unchanged 14 months after the radiosurgery.
