Abstract:Trigeminal neuralgia is a common clinical neuropathic pain, with intermittent severe pain in the unilateral or bilateral trigeminal nerve distribution area as the main clinical manifestation. The use of radiofrequency thermocoagulation for the treatment of trigeminal neuralgia has the advantages of small trauma, high pain relief rate, low recurrence rate and less postoperative complications. It has been widely used in clinical practice in recent years. This review summarizes clinical research of different temperatures used in radiofrequency thermocoagulation for the treatment of trigeminal neuralgia and discusses the effect of temperature on surgical outcomes. Currently,65℃ -75 °C is the preferred temperature range for treatment. What is more, when selecting the temperature, it is necessary to take age, disease characteristics and expectations of treatment effect of each single patient into concern to improve the treatment effect and patient satisfaction.
