Radiofrequency thermocoagulation combined with pulsed radiofrequency helps relieve postoperative complications of trigeminal neuralgia . Trigeminal neuralgia is a sudden , severe condition characterized by stabbing and recurrent pain . Radiofrequency thermocoagulation ( RFT ) and pulsed radiofrequency ( PRF ) are common surgical interventions used to treat trigeminal neuralgia . This study aimed to investigate the therapeutic effects and associated complications of a combination of RFT and PRF in the treatment of trigeminal neuralgia . Computed tomography-guided percutaneous RFT of the Gasserian ganglion was performed on 80 patients with trigeminal neuralgia . Patients were randomly assigned to either group A ( RFT at 70°C ) or group B ( RFT at 75°C ) . Patients in each group were divided into 2 subgroups , receiving percutaneous RFT ( 240 s ) with or without PRF ( 42°C , 2 Hz , 240 s ) . Six months later , pain relief and complication status were evaluated . There was no significant difference in visual analogue scores among groups with RFT at 70° or 75°C , with or without PRF . Data showed that facial numbness and postoperative masticatory muscle weakness recovered more rapidly in patients receiving combined RFT and PRF treatment . Decreased corneal reflex was relieved to a significantly greater extent in groups receiving PRF than those without . Thus , compared to the use of RFT at 75°C alone , the combination of PRF and RFT helped eliminate postoperative complications , such as facial numbness , masticatory muscle weakness , and decreased corneal reflex , indicating that it could be useful for surgically treating trigeminal neuralgia .
