Figures & data
Figure 1. Surgical schematic of PNS implantation and PRF placement. (a) Anteroposterior view of fluoroscopic imaging. Red cycle indicated the foramen ovale; blue line indicated the mandibula; (b) depth of PRF cannulation was guided under the lateral view of the fluoroscopy.

Figure 2. Pain severity assessed by the visual analogue score at each follow-up point. Patients were interviewed at baseline, discharge, 1-, 3-, 6- and 12 months after neuromodulation treatment. Two-way analysis of variance with repeated measures and Bonferroni’s post-test. ns = non-significant, *p < .05, **p < .01, ****p < .0001.
