ABSTRACT
BACKGROUND:
This study aimed to investigate the treatment efficacy and clinical and demographic characteristics affecting treatment success in patients who underwent ultrasound (US)-guided pulsed radiofrequency (PRF) to the maxillary and/or mandibular nerves for trigeminal neuralgia.METHODS:
The data of patients with trigeminal neuralgia who underwent US-guided maxillary and/or mandibular nerve PRF between September 2022 and December 2023 were reviewed and the study was retrospectively designed. Good analgesia was defined as ≥ 50% reduction in pain score at 3 months after the procedure, and the demographic and clinical characteristics of the patients were assessed.RESULTS:
Among the 72 included patients, 39 (54.2%) and 33 (45.8%) were classified as responders and non-responders, respectively. The age, pre- and post-procedural Numerical Rating Scale (NRS) scores, pain duration, and presence of constant pain were significantly lower in the responders. Logistic regression analysis revealed that older age (OR = 0.899, p < 0.001), high pre-procedural NRS scores (OR = 0.177, p = 0.009) and non-idiopathic (secondary or classic) etiology (OR = 0.062, p = 0.048) were significantly associated with an unsuccessful response to maxillary/mandibular PRF treatment.CONCLUSION:
This study is the first clinical trial to evaluate the efficacy of PRF therapy of the maxillary and mandibular nerves in the treatment of trigeminal neuralgia and demonstrated a significant reduction in pain scores at 3 months. Older age, high pre-procedural NRS scores, and non-idiopathic (secondary or classical) etiology are independent predictors of poor response to ultrasound-guided maxillary/mandibular nerve pulse radiofrequency treatment.
