Answer

Answer

With PBM, the operator inserts a balloon catheter through the foramen ovale into the region of the ganglion and inflates it for 1-10 minutes. PRTG has gained wide acceptance according to several investigators, because the patient  recovers quickly, and goes home the day of the procedure or the next day.

According to Tan et al, the recurrence rate approaches 25% with PRTG, and occasionally patients suffer complications of jaw weakness and corneal anesthesia. As related by Meglio and Cioni, some surgeons report excellent results with PBM, which are comparable to those with PRTG. [11]
