    Endoscopic neurotomy (EN) and radiofrequency ablation (RFA) were compared for long-term pain relief in cervicogenic headache (CEH) patients.

  • 2

    Both EN and RFA significantly reduced pain and improved quality of life at 3 and 12 months postoperatively compared to baseline.

  • 3

    EN demonstrated superior effectiveness over RFA at 12 months, with longer median pain-free duration of 33 months versus 8 months.

  • 4

    Patient Global Impression of Change (PGIC) favored EN at both 3 and 12 months, indicating better overall patient satisfaction.

  • 5

    No serious adverse events occurred, but occipital-distribution numbness was reported in both treatment groups.
