Abstract
Aim
To evaluate the efficacy of the Centella asiatica extract in a cream preparation for
the prevention of scar tenderness formation in patients who underwent conventional
open carpal tunnel release (CTR) surgery.
Material and Methods
A total of 280 patients with carpal tunnel syndrome who underwent CTR surgery were
individually randomized into the intervention (n = 140) and control (n = 140) groups.
In the intervention group, a petroleum cream mixture consisting of 1% Centella asiatica
extract was applied to the patients’ wrist for 6 months after the sutures were removed.
In the control group, no intervention was applied. The Vancouver Scar Scale (VSS),
Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) functional score, and Visual
Analog Scale (VAS) satisfaction scores were assessed preoperatively and postoperatively.
Follow-up evaluations were scheduled at 1, 3 and 6 months after CTR surgery.
Results
The overall VSS score of the intervention group significantly improved at 3-6 months
(-1.260, p = .040). At 6 months after surgery, the mean QuickDASH functional score was 18.54
(range 0.00-63.64, SD 17.4) in the intervention group and 28.70 ± 12 (range: 2.27-40.91)
in the control group (p < .04). At 6 months after surgery, the mean VAS satisfaction score was 1.46 ± 1.95
(range: 0-4) in the intervention group and 2.48 ± 1.02 (range: 0-4) in the control
group (p < .03).
Conclusion
The Centella asiatica cream applied to the wrist after CTR surgery was found to be
beneficial in preventing scar tenderness in the thenar and hypothenar regions of the
hand.
