Abstract
Objective: Endoscopy-assisted surgical procedures for CTS has become increasingly prevalent since 1990s. In endoscopy-assisted carpal tunnel release surgery (EACTRS), it has been proposed that nerve damage likelihood is similar to other procedures. It has also been proposed that EACTRS is especially associated with smaller scar size, painless and faster recovery period. We aimed to determine our clinical and functional results in patients with EACTRS and compare them with the literature
Method: We evaluated 25 (39 hands ) patients who underwent endoscopy-assisted carpal tunnel release surgery between 2012 and 2017. In all patients, demographic characteristics, preoperative- postoperative functional scores, patient satisfaction levels and time required to return-to-work were recorded;
Results: The endoscopy-assisted carpal tunnel release surgery had positive significant effect on patient satisfaction scores(p<0.05). A statistically significant difference was found between those with and without Double Crush syndrome (DCS) in favor of those without DCS in terms of pre- and postoperative BTCQ symptom severity score (p<0.05). We found only two scar tenderness and two revision Carpal Tunnel release .
Conclusion: The EACTRS is an effective method in the treatment of carpal tunnel syndrome. Clinical outcomes are comparable to other methods. Those with DCS, those with comorbidities, and female gender were evaluated as negative prognostic factors in patients who underwent EACTRS.
