Abstract：Objective To investigate the efficacy and safety of long-duration pulsed radiofrequency(LDPR)of the dorsal root ganglion combined with paravertebral nerve block(PVB)in middle-aged and elderly patients with postherpetic neuralgia(PHN).Methods A retrospective analysis included 106 middle-aged and elderly PHN patients treated at Jiangyou 903 Hospital from January 2022 to January 2025.Patients receiving conventional radiofrequency treatment were assigned to the control group(n=53),while patients receiving dorsal root ganglion LDPR combined with PVB were assigned to the observation group(n=53).Clinical efficacy,changes in Visual Analog Scale(VAS)and Pittsburgh Sleep Quality Index(PSQI)scores,and the incidence of adverse reactions were evaluated in both groups.Results The total effective rate was 88.68%in the observation group,significantly higher than 71.70%in the control group(P<0.05).At post-treatment time points T1～T4,VAS and PSQI scores decreased in both groups,with scores consistently lower in the observation group compared to the control group.Significant group main effects,time main effects,and interaction effects were observed(P<0.05).No serious adverse reactions occurred in either group during treatment.The difference in the total incidence of adverse reactions was not statistically significant(P>0.05).Conclusion Dorsal root ganglion LDPR combined with PVB demonstrates good clinical efficacy and safety in treating middle-aged and elderly PHN patients,indicating significant clinical application value.
