Abstract:Objective: To explore the clinical efficacy of Gasserian Ganglion Pulsated Radiofrequency (GG-PRF) in the treatment of facial Zoster Associated Neuralgia (ZAN), as well as the risk factors that affect its therapeutic effect by retrospectively analysis. This study aims to provide more valuable reference for screening treatment populations and predicting long-term treatment outcomes for GG-PRF therapy. Methods: From January 1,2018 to June 30, 2023, clinical data of patients with facial ZAN and receiving GG-PRF treatment at Department of Pain Management of Shandong Provincial Hospital, Cheeloo College of Medicine were collected. The Numerical Rating Scale (NRS) and Simple Sleep Index were used to record the pain level and sleep status of patients before GG-PRF treatment, as well as at discharge, at 3 months, at 6 months, and 1 year after GG-PRF treatment. Simultaneously, the occurrence of adverse events during treatment were recorded. Retrospective analyze the clinical efficacy of GG-PRF, using univariate and multivariate logistic analysis to screen for factors that may affect efficacy. Results: A total of 70 patients were included in the analysis. The NRS scores significantly decreased (P<0.001), and the sleep quality significantly improved (P<0.001) after GG-PRF treatment. Only 2 adverse events occurred, and they recovered quickly after symptomatic treatment. The Logistic analysis showed that Course (OR 2.207, 95% CI 0.946-5.145, P=0.012) was the risk factor. Conclusion: GG-PRF treatment is safety and effective in the treatment of facial ZAN patients, which can effectively alleviate pain and improve sleep quality. Course is the risk factor affecting treatment effectiveness, it is recommended that patients with facial ZAN should be treated as early as possible.
