Objective The small incision sub-palmar aponeurotic transverse carpal ligament incision under the guidance of safe angle is a treatment of carpal tunnel syndrome. This article is aimed to discuss this treatment’s clinical therapeutic effect. Methods From June 2015 to June 2018, 105 cases (112 sides) of carpal tunnel syndrome were treated by small incision sub-palmar aponeurotic transverse carpal ligament incision under the guidance of safe angle. 14 sides had lysis of adventitia of median nerve under direct vision. Results All incisions had primary healing, the palm scars were mild, and no operative complications happened. We followed 112 sides after the surgery. The follow-up time was 6-24 months. Result showed that according to Kelly classification, 93 sides were ranked to excellent, 15 were good and 4 were fair. The excellent and good rate was 93.1%. Conclusions Small incision sub-palmar aponeurotic transverse carpal ligament incision under the guidance of safe angle is one of the ideal minimal invasive operations to treat carpal tunnel syndrome. This operation is simple, safe and can meet the needs of carpal tunnel decompression and neurolysis
