In PRTG, a radiofrequency heating tip sears the ganglion until the area of facial pain becomes numb. This procedure has gained wide acceptance according to several investigators, because the patient is awake during the procedure, recovers quickly, and goes home the day of the procedure or the next day. However, according to Tan et al, the recurrence rate approaches 25% with PRTG, and occasionally patients suffer complications of jaw weakness and corneal anesthesia. [58]
