X-knife stereotactic radiosurgery on the trigeminal ganglion to treat trigeminal neuralgia: a preliminary study.
Stereotactic radiosurgery is an attractive option for elderly patients and those who do not tolerate the more invasive surgical procedures available for trigeminal neuralgia (TN). In the majority of the studies, the target location was designated as the proximal nerve at the root entry zone (REZ). The purpose of this article was to evaluate the efficacy of and complications associated with X-knife stereotactic radiosurgery on the trigeminal ganglion (TG) for TN. ⋯ Similar to other TN radiosurgery reports, X-knife stereotactic radiosurgery for TN provides effective pain relief with a low complication rate.

We present our experience using a standardized transnasal transclival approach (TTA) for endoscopic removal of chordomas of the clivus. ⋯ The TTA provides an elegant alternative to classical approaches to clival lesions especially for midline tumor locations. For large tumors iMRI is of significant help. Dural reconstruction of large defects emerged as the greatest challenge of this technique even for experienced endoscopic surgeons.
