Technical considerations for facilitation of selective percutaneous radiofrequency neurolysis of the trigeminal nerve

Fine points of the technique of selective percutaneous radiofrequency trigeminal neurolysis relative to patient preparation accurate and rapid foramen ovale puncture, electrode positioning, and neurolytic lesions are discussed. These measures. which have evolved from our experience in treating trigeminal neuralgia by this method over the last 4 years, have made the procedure safer and less painful but also significantly more expedient.
