A stereotactic frame for trigeminal ganglionectomy.

A special stereotactic frame (Radionics) is dedicated to percutaneous electrocoagulation of the trigeminal ganglion. It permits a selection of the first, second or third rootlet according to the territory involved with pain. The penetration of the foramen ovale may be achieved by a jugal or a submaxillary approach, with a common fluoroscopic survey.
