Impar Ganglion Block with Combination of Neurolysis Drugs and Radiofrequency Thermocoagulation for Perineal Pain.

Since it was first introduced, a variety of modification techniques to block the impar ganglion appear such as transsacrococcygeal ligament technique, sacrococcygeal transdiscal approach, paramedian approach, and a two-needle technique using fluoroscopy or computed tomography scan. For therapeutic purposes, a combination of steroid and local anesthetic, neurolysis agents such as alcohol, phenol, cryolesioning, and heat lesioning using radiofrequency thermocoagulation could be used. Here, we reported a successful outcome in treating chronic perineal pain in a 65-year-old patient using combination of neurolysis agent which was alcohol 96% and radiofrequency thermocoagulation.
