Radiofrequency thermocoagulation(RFT)of the gasserian ganglion is a routine and effective technique for the treatment of classical trigeminal neuralgia(CTN).In this study we compared its efficacy in patients with CTN and atypically symptomatic or mixed trigeminal neuralgia(MTN).Fifty-seven patients were treated with RFT for trigeminal neuralgia from June 2006 to February 2009.Thirty patients had CTN,and 27 had MTN.Outcomes were measured by using the visual analog pain scale(VAS)and patients' reports of quality of life(QOL),medication usage,and complications over a follow-up period of up to 3 years.Our results showed that the patients with MTN were younger,tended to have bilaterial involvement of the first division,and were unresponsive to treatment.All surgeries were completed smoothly.About 86.7% CTN patients and 48.1% MTN patients responded immediately to RFT.The VAS scores were significantly higher in the CTN group than in MTN group(P
