[Selective percutaneous thermocoagulation of the glossopharyngeal nerve in intractable glossopharyngeal neuralgia].
Percutaneous radiofrequency thermocoagulation of glossopharyngeal nerve at the jugular foramen was employed for the treatment of intractable glossopharyngeal neuralgia in three cases, one with essential and two with symptomatic pain from malignant tumor of the oropharyngeal area. Under radiological control, the thermocoagulation electrode was inserted through the lateral cervical route, and the electrode reached the jugular foramen with the tip toward the pars nervosa. The correct position of the electrode was confirmed by radiography and by electrophysiological stimulation test. Once the electrode was properly positioned, lesion was made with temperature of 60 degrees C to 70 degrees C for 1 approximately 2 minutes. Surgical results were satisfactory and no neurological and cardiovascular complications were noted. Percutaneous radiofrequency thermocoagulation of glossopharyngeal nerve is thought to be very useful for the treatment of intractable glossopharyngeal neuralgia.
