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.
