Background: Percutaneous radiofrequency thermocoagulation (PRFT) has been widely used to treat trigeminal neuralgia. By querying MEDLINE, EMBASE, and the Cochrane Library, no study has reported the long-term outcome of PRFT for tumor-related trigeminal neuralgia (TRTN). Objectives: In this study, we aimed to evaluate the long-term efficacy and safety of PRFT as an alternative treatment for TRTN. Study Design: A retrospective study. Setting: The interventional pain management center in Beijing Tiantan hospital. Methods: We retrospectively analyzed data of all patients who underwent PRFT applied to the Gasserian ganglion under computed tomography guidance for TRTN through a combination of available institutional electronic medical records, patient notes, and radiologic images. Results: Among 38 patients with PRFT treated between March 2007 and February 2018, 13 patients were men and 25 were women. All patients were evaluated as modified Barrow Neurological Institute (BNI) IV-V before the operation and had a total symptom duration of 45.55 ± 23.31 months. The mean operation duration was 59.63 ± 16.89 minutes. All patients experienced satisfactory pain relief defined as a classification of BNI I-IIIb within 3 days after PRFT. The median remission length with satisfactory pain relief was 33 (range, 4-132) months. No serious intraoperative complications, except bradycardia in 6 patients, were recorded. Postprocedure complications, including masticatory muscle weakness, were reported in 5 patients. Although all 38 patients experienced facial dysesthesia, the patients’ Likert scale rating represented that quality of life significantly increased after the procedure. Limitations: The small sample size may have unavoidably caused selection bias in our study. Larger prospective, randomized, multicenter trials are necessary to validate our outcomes. Conclusions: PRFT is an effective and safe treatment that should be considered as an alternative for pain control in the treatment of TRTN.

Abstract Background and Objective Microsurgical vascular nerve decompression and percutaneous ablative interventions aiming at the Gasserian ganglion are promising treatment modalities for patients with medical refractory trigeminal neuralgia (TN). Apart from clinical reports on a variable manifestation of facial hypoesthesia, the long-term impact of trigeminal ganglion radiofrequency thermocoagulation (RFT) on sensory characteristics has not yet been determined using quantitative methods. Material and Methods We performed standardized quantitative sensory testing according to the established protocol of the German Research Network on Neuropathic Pain in a cohort of patients with classical (n = 5) and secondary (n = 11) TN before and after percutaneous Gasserian ganglion RFT (mean follow-up: 6 months). The test battery included thermal detection and thermal pain thresholds as well as mechanical detection and mechanical pain sensitivity measures. Clinical improvement was also assessed by means of renowned pain intensity and impairment questionnaires (Short-Form McGill Pain Questionnaire, Pain Disability Index, and Pain Catastrophizing Scale), pain numeric rating scale, and anti-neuropathic medication reduction at follow-up. Results All clinical parameters developed favorably following percutaneous thermocoagulation. Only mechanical and vibration detection thresholds of the affected side of the face were located below the reference frame of the norm population before and after the procedure. Statistically significant persistent changes in quantitative sensory variables caused by the intervention could not be detected in our patient sample. Conclusion Our data suggest that TN patients improving considerably after RFT do not undergo substantial long-term alterations regarding quantitative sensory perception.

BACKGROUND: Radiofrequency thermocoagulation through the supraorbital foramen with a different puncture method is a new approach for the treatment of ophthalmic division trigeminal neuralgia. OBJECTIVES: To compare the efficacy of the vertical puncture method and the transverse puncture method in the treatment of ophthalmic division trigeminal neuralgia during radiofrequency thermocoagulation through the supraorbital foramen. STUDY DESIGN: Randomized, longitudinal prospective, clinical research study. SETTING: Department of Anesthesiology and Pain Medicine, Jiaxing, China. METHODS: A total of 57 patients with ophthalmic division trigeminal neuralgia were enrolled in the study between October 2011 and April 2018, and prospectively randomized into the vertical puncture group (n = 29) or transverse puncture group (n = 28). All these patients received computed tomography guided radiofrequency thermocoagulation through the supraorbital foramen. Patients in the vertical puncture group were treated with a vertical puncture method; patients in the transverse puncture group received a transverse puncture method. Facial pain was evaluated using the Numeric Rating Scale preoperatively and at 1 day, 6 months, 1 year, and 2 years after treatment; facial numbness degree was analyzed at 1 day and 2 years after the treatments were recorded. The short-term and long-term complications during the period of postoperative follow-up were recorded. RESULTS: All surgical procedures were successfully completed. The Numeric Rating Scale scores at 6 months, 1 year, and 2 years after the treatment were significantly lower in the transverse puncture group compared to the vertical puncture group (P < 0.05), while no difference was observed on day one after the treatment (P > 0.05). The numbness degree at 2 years was significantly decreased compared to day one in both groups (P < 0.05). The radiofrequency thermocoagulation for ophthalmic division trigeminal neuralgia in the transverse puncture group showed better long-term outcomes than those in the vertical puncture group (P < 0.05). No short-term or long-term postoperative complications were observed in any of the groups. LIMITATIONS: Additional clinical data should be collected to preserve the results in future work. CONCLUSION: The transverse puncture method during radiofrequency thermocoagulation through the supraorbital foramen had better efficacy and fewer complications in comparison with the vertical puncture method when treating ophthalmic division trigeminal neuralgia.

Lethal Complications

Trigeminal neuralgia (TN) is a common neuropathic pain that seriously affects the daily life of patients. Many invasive treatments are currently available for patients who respond poorly to oral carbamazepine or oxcarbazepine. Among them, radiofrequency (RF) treatment is a viable option with reliable initial and long-term clinical efficacy. The long-term analgesic effects of radiofrequency thermocoagulation (RFT) at high temperatures (≥80°C) are not superior to those at relatively low temperatures (60–75°C). In contrast, the higher the temperature, the greater the risk of complications, especially facial numbness, masticatory muscles weakness, and corneal hypoesthesia. Some patients even experience irreversible lethal complications. Therefore, we recommend low-temperature RFT (60–75°C) for treatment of TN. The therapeutic effects of pulsed radiofrequency (PRF) are controversial, whereas PRF (≤75°C) combined with RFT can improve long-term effects and decrease the incidence of complications. However, large-scale clinical trials are needed to verify the efficacy of the combination of PRF and RFT.
