Pain-free survival after endoscopic neurotomy versus radiofrequency ablation of the C2 dorsal root ganglion for cervicogenic headache: a real-world comparison study
To compare long-term outcomes of endoscopic neurotomy (EN) versus radiofrequency ablation (RFA) targeting the C2 dorsal root ganglion in patients with cervicogenic headache (CEH), highlighting the significance of this comparison.
Key Findings:
Both EN and RFA groups showed significant reductions in NRS and improvements in EQ-5D-5L at 3 and 12 months postoperatively (P < 0.001).
NRS and EQ-5D-5L outcomes were comparable at 3 months (P > 0.05), but EN showed superior effectiveness at 12 months (P < 0.05).
PGIC favored EN at both 3 and 12 months (P < 0.05).
Median pain-free duration was significantly longer in the EN group (33 months) compared to the RFA group (8 months) (P < 0.05).
Interpretation:
Both EN and RFA improved pain and quality of life in CEH patients, with EN associated with longer pain-free duration; however, EN's invasiveness necessitates careful patient selection and consideration of potential risks.
Limitations:
The study is retrospective and conducted at a single center, which may limit generalizability.
The sample size for EN was relatively small (21 patients), which may affect the robustness of the findings.
Potential biases in patient selection and treatment allocation should be acknowledged, as well as confounding factors that may influence outcomes.
Conclusion:
EN may provide longer-lasting pain relief compared to RFA in CEH patients, but should be approached cautiously due to its invasive nature; further research is needed to validate these findings.
