Objective: Besides being the most frequent nevre compression syndrome of upper extremity, carpal tunnel syndrome is one of the most common cause of labor loss. Although open surgical procedures have good results for the treatment of this syndrome, endoscopic approaches have been popularised for the reason of lessening the morbidity rates and time for returning to work. In this study, the effectiveness of the surgical procedures on complications, patient satisfaction and return to daily living activities are compared. Material and Methods: Thirty patients who had the diagnose of severe carpal tunnel syndrome between February 2005 and February 2006 had undergone to surgery with random selection as 15 open and 15 endoscopic methods. The mean age was 37.7 years. All of the patients were questioned in the first postoperative month for usage of their hands on daily living activities with Boston carpal tunnel syndrome quetionnaire. Results: Avarage period for returning to work in the open and endoscopic methods were 30 and 18 days respectively. There were no significant statistical difference in terms of functional results and patient satisfaction. Wound haematoma and superficial infection were seen at a higher rate in patients who under went open surgery. There was no permanent nevre injury as a complication during the postoperative period in both patient groups. Conclusion: In our study, although there was no significant statistical difference in terms of patient satisfaction and functional scores on both endoscopic and open surgery performed patient groups, endoscopic surgery is an alternative choice of treatment method due to lower complication rates and short return to work periods for active workers and patients who are expected to have wound problems in the postoperative period.
