Abstract
OBJECTIVE
The purpose of this study was to determine any differences in outcome and patient satisfaction between endoscopic release (ECTR) and open carpal tunnel release (OCTR) in patients with bilateral carpal tunnel syndrome who underwent both techniques.
METHODS
Seven patients with confirmed bilateral idiopathic carpal tunnel syndrome were randomized to undergo endoscopic release using a single portal Agee technique to one hand and a minimal open release to the other. Subsequent assessments were made at 0, 3, and 12 months after operation using a modified Levin scale. We also analyzed subjective and objective outcomes retrospectively, including the time to return to full activity, patient preference, cosmetic satisfaction, scar tenderness, and pillar pain. The pain was assessed using a visual analogue scale from 1 to 10.
RESULTS
Based on the Levin scale, there were no significant differences between hands at any follow-up interval. At the three-month follow up, mean scale scores were lower in the ECTR group; however, the differences did not reach statistical significance. Cosmetically, all patients were satisfied with their scar irrespective of the technique. There were no statistical differences in terms of scar tenderness and pillar pain.
CONCLUSION
ECTR did not show any significant advantage over short-incision OCTR. Therefore, the operator's experience and skill in using a certain method is important, regardless of which technique is used.
