“…In this study, the incidence of postoperative facial numbness in groups A and B was 85 and 86%, respectively, different from those in the study previously performed by Fraioli et al (2009). This difference was probably due to the disparate RFT temperatures used between the two studies.…”

ABSTRACT. 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.

“…The immediate pain relief rates in group A and B were 94.3 and 97.6%, respectively, lower than those reported in the literature (Fraioli et al, 2009). Previous studies have reported immediate pain relief rates from RFT in the treatment of TN between 91-99% (Bovaira et al, 2013;Kim et al, 2013;Weng et al, 2013).…”

“…Many therapies have been proposed for the treatment of medically refractory trigeminal neuralgia: anatomically destructive methods, including retrogasserian rootlet thermocoagulation [14][15][16] , and percutaneous balloon compression; 17 and anatomically nondestructive methods, including gasserian ganglion glycerolrhizolysis, 18,19 and microvascular decompression. 20 Non-invasive procedures are also performed, including various types of RS.…”

a b s t r a c tRadiosurgery (RS) and hypofractionated stereotactic radiotherapy (HSRT) were performed in 23 and 22 patients respectively for the treatment of trigeminal neuralgia. RS and HSRT were performed with a dedicated linear accelerator (LINAC): an invasive frame (for RS) or a relocatable stereotactic frame fitted with a thermoplastic mask and bite blocks (HSRT) were used for positioning patients. The RS treatment delivered 40 Gy in a single fraction, or for HSRT, the equivalent radiobiological fractionated dose -a total of 72 Gy in six fractions. The target (the retrogasserian cisternal portion of the trigeminal nerve) was identified by fusion of CT scans with 1-mm-thick T2-weighted MRI, and the radiant dose was delivered by a 10-mm-diameter cylindrical collimator. The results were evaluated using the Barrow Neurological Institute pain scale during follow-up (mean 3.9 years). The 95% isodose was applied to the entire target volume. After RS (23 patients), Class 1 results were observed in 10 patients; Class II in nine, Class IIIa in two, Class IIIb in one, and Class V results in one patient. Facial numbness occurred in two (8.7%) patients, and the trigeminal neuralgia recurred in two patients (8.7%). Following HSRT (22 patients), Class I results were achieved in eight patients, Class II in eight, Class IIIa in four, and Class IIIb in two patients; recurrence occurred in six (27.5%), and there were no complications. Thus, both RS and HSRT provided effective and safe therapy for the treatment of trigeminal neuralgia. Patients who underwent RS experienced better pain relief and a lower recurrence rate, whereas those who underwent HRST had no side effects, and in particular, no facial numbness.

“…We used a temperature of 65°C for all the patients being well tolerated and safe. It's wellknown that serious complications often occur at a temperature ≥70°C [16][17][18]. Our opinion is that the optimal temperature should be between 60 and 65°C.…”

“…In addition, information on temperature used for CRF for V1 TN was not mentioned in some reports [19,20]. Using previous reports information [1,12,[17][18] we adjusted the temperature to less than 70°C and all the procedure was performed under general anesthesia. Facial numbness was found the most frequent transient complication (19%) that improved in more than 50% after 2 months and almost 90% in 10 months.…”
