Abstract:
Objective To study the effects of pulsed radiofrequency(PRF)and radiofrequency thermocoagulation(RFTC)in the treatment of idiopathic infraorbital neuralgia.Methods 16 patients suffering idiopathic infraorbital neuralgia were randomly divided into PRF(n=8)and RFTC(n=8).Numeral rating scale(NRS),pain relief(PR)and effective rate of treatment was performed before operation and at 1 hour、1 st day、7th day、15th day、1 st month、3rd month and 6th month after operation.Results The preoperative and postoperative impedance of thefirst,second and third operation in RFTC group were(490±86)Ω and(424±82)Ω,(492±90)Ω and(432±84)Ω,(481±98)Ω and(409±85)Ω respectively and the postoperative impedance was significantly decreased(P＜0.05).The preoperative NRS in group PRF and RFTC were 9(7～10)and 8.5(7～10)respectively and the postoperative NRS at all points in two groups were significantly decreased as compared with the preoperative NRS(P＜0.05).The PR at 7 and 15d in group PRF were 3(0～4)and that in group RFFC were 4(3～4)(P＜0.05).There were no significant differences in effective rate of treatment at each time between two groups(P＞0.05).Numbness appeared after operation in group PRF and disappeared in a week,however,that was persistent and all sense disappeared in group RFTC.Conclusion Curative effect of PRF for idiopathic infraorbital neuralgia is as well as RFTC and it is a kind of safe and effective technology that causes less side effects.
