Percutaneous thermocoagulation for sphenopalatine ganglion neuralgia

The authors describe percutaneous radiofrequency (rf) thermocoagulation of the sphenopalatine ganglion used to treat seven patients with sphenopalatine ganglion neuralgia. The procedure was effective in relieving pain, without significant side-effects. All the patients have actually been free of pain during a follow-up of 6-28 months. The surgical technique and the rationale for its use are pointed out.
