Abstract

Objective: To evaluate the outcomes of endoscopic release of the transverse carpal ligament (TCL) in carpal tunnel syndrome (CTS) using the Chow dual-portal technique between January 2006 and December 2015. Materials and Methods: Study population consisted of 217 cases of idiopathic CTS, in 179 patients, 145 females (81%) (31 bilateral cases) and 34 males (19%) (7 bilateral cases), with an average age of 48.2 years (range, 32-68) and an average follow-up of 97.9 months. The symptom severity and functional evaluations were performed using the Boston Carpal Tunnel Questionnaire Symptoms Severity Scale (BCTQ-SSS)and the Functional Status Scale (BCTQ-FSS). Results: The average BCTQ-SSS was 3.20+0.26 in the preoperative period, which improved to 1.30+0.12 at the 6-month postoperative follow-up and remained at 1.25+0.11 in the long-term. The average BCTQ-FSS was 2.57+0.29 in the preoperative period, which improved to 1.28+0.12 at the 6-month postoperative follow-up and remained at 1.20+0.09 in the long-term. There were 7 cases (3.2%) of transient postoperative neurapraxia. No patient required to be converted to open technique. Conclusion: The endoscopic carpal tunnel release with Chow technique is an effective and safe surgical method for the treatment of idiopathic CTS.
