ABSTRACT
Objective:
This study aimed to evaluate the clinical effects of medial branch blocks (MBB) C2 and C3 in treating patients with medically intractable headaches.Methods:
The medical records of 81 patients with medically intractable headaches who underwent a C2/3 MBB between January 2019 and March 2022 were retrospectively reviewed. The degrees of pain were evaluated using a visual analogue scale (VAS) score (rating 0-10) on baseline and after procedures. To evaluate patients' satisfaction for the treatment, self-reporting measurements were examined and were categorized as excellent (>90% pain relief), good (50%-90% pain relief), fair (10%-50% pain relief), and none (<10% pain relief).Results:
The total number of MBB procedure was 107. The average baseline VAS score was 7.4 ±1.5, which improved significantly to 2.6 ±2.3, 3.6 ±2.6, and 4.5 ±3.2 on 1-3 days, 3-7 days, and 3 months after the procedure, respectively (Wilks' lambda within group test, P <0.001). For the subjective feeling of pain relief, percentages of "excellent" response in the self-reporting measurements were significantly decreased over time (chi-square test; P= 0.001).Conclusion:
This study demonstrates clinical effectiveness of C2/3 MBB in patients with medically intractable headaches, with both early and prolonged benefits.
