Observational study shows that repeat radiofrequency thermocoagulation improves outcomes in trigeminal neuralgia, suggesting limited reintervention may be optimal.

However, its benefits diminish, and risks increase with each additional procedure, particularly the third. Based on these findings, reintervention should generally be limited to a single repeat procedure.
