SurgView-RFT Electromagnetic Navigation System in Trigeminal Ganglion RF Therapy

Abstract

Percutaneous radiofrequency thermocoagulation of the trigeminal ganglion (PRTTG) is demonstrated as the first choice for most patients suffering trigeminal neuralgia (TN). The purpose of this study was to assess the safety and efficacy of SurgView-RFT electromagnetic navigation system in PRTTG therapy of intractable TN. Experiments including head model of human, live goat, cadaver guarantee the accuracy of the system. 3 cases of TN were underwent CT positioning with RFT in our department after a follow up observation of 3-24 months. All the patients got successful procedure with pain relief and without recurrence and complications such as hematoma, tinnitus and corneal palsy. SurgView-RFT electromagnetic navigation system overcomes the disadvantage of traditional positioning method and is a safe and promising method for treatment of intractable TN with better short- and long-term outcomes and lower complication rate. It is proved that the system has significant clinical clinical value.
