AI Article Synopsis
- A study was conducted to assess the effectiveness and safety of radiofrequency thermocoagulation (RFT) on patients with idiopathic trigeminal neuralgia (ITN), focusing on finding the best temperature for treatment.
- The study involved 1,137 patients who underwent RFT procedures; outcomes were measured based on pain relief and the severity of facial numbness, with temperatures divided into three groups (≤75°C, 75°C, and ≥80°C).
- Results indicated no significant differences in pain relief among the temperature groups, but patients treated at 75°C experienced less severe facial numbness, suggesting it might be the optimal temperature, though further confirmation is needed.
Article Abstract
Objective: Our previous study evaluated the effectiveness and safety of radiofrequency thermocoagulation (RFT) of trigeminal gasserian ganglion for idiopathic trigeminal neuralgia (ITN). The aim of this study was to evaluate the optimal radiofrequency temperature of computed tomography (CT)-guided RFT for treatment of ITN.
Methods: A retrospective study of patients with ITN treated with a single CT-guided RFT procedure between January 2002 and December 2013. Patients were divided into ≤75 °C, 75 °C, and ≥80 °C groups according to the highest radiofrequency temperature used. Pain relief was graded from poor to excellent, and facial numbness/dysesthesia from I (absent) to IV (most severe).
Results: A total of 1161 RFT procedures were undertaken in the 1137 patients. The mean follow-up time was 46 ± 31 months. There were no significant differences in the rate of excellent pain relief according to the radiofrequency temperature used. However, more patients experienced with no facial numbness or facial numbness gradually resolved and those patients treated at 75 °C had a lower rate of grade IV facial numbness/dysesthesia than other groups.
Conclusions: The optimal radiofrequency temperature to maximize pain relief and minimize facial numbness or dysesthesia may be 75 °C, but this requires confirmation.
