Effect of Repeated Pulsed Radiofrequency for Trigeminal Herpes Zoster Neuralgia: A Retrospective Study.
Article in Journal of pain research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The quality of life for patients suffering from trigeminal herpes zoster neuralgia (TG-HZN) is significantly compromised due to the persistent pain associated with this condition. Pulsed radiofrequency (PRF) has emerged as an effective treatment option. Currently, most patients opt for a single PRF treatment; however, some individuals report inadequate analgesic effects, short durations of pain relief, and overall instability in efficacy. Repeated PRF may enhance therapeutic benefits and improve patient satisfaction. Objective: This retrospective study aimed to evaluate the efficacy of repeated PRF compared to a single PRF in patients with TG-HZN. Patients and Methods: We conducted a retrospective analysis of data from 107 TG-HZN patients who underwent CT-guided selective extracranial PRF neurolysis targeting the mandibular branch within the foramen ovale during a one-week hospitalization period. Participants were divided into two groups: single PRF (once PRF, Group S-PRF) and repeated PRF (twice PRF, Group R-PRF). To assess outcomes pre- and post-treatment, we utilized the numeric rating scale (NRS), Pittsburgh Sleep Quality Index (PSQI), and measured the incidence of clinically significant trigeminal postherpetic neuralgia (TG-PHN). Results: The NRS and PSQI scores of the group R-PRF were significantly lower than those of the group S-PRF at the 1st, 4th, 8th, 12th, and 24th weeks post-treatment ( Conclusion: Repeated pulsed radiofrequency treatments demonstrated substantial efficacy in managing trigeminal herpes zoster neuralgia while also exhibiting superior effectiveness in decreasing the incidence of clinically significant trigeminal postherpetic neuralgia.
