Surgical management of trigeminal schwannomas: defining the role for endoscopic endonasal approaches.

摘要: Object Because multiple anatomical compartments are involved, the surgical management of trigeminal schwannomas requires a spectrum cranial base approaches. The endoscopic endonasal approach to Meckel's cave provides minimal access corridor for surgery, but few reports have assessed outcomes procedure or provided guidelines case selection. Methods A prospectively acquired database 680 cases was queried schwannoma cases. Clinical charts, radiographic images, and long-term were reviewed determine outcome success in removing tumor from each compartment traversed by nerve. Results Four patients had undergone resection via transpterygoid (mean follow-up 37 months). All disease within cave, 1 patient extension into posterior fossa. Gross-total achieved 3 whose tumors purely extracranial. One with combined ...
