Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment. Diagnosis is based on symptoms, clinical findings and electrophysiological examination. Several conservative and surgical treatment options have been described.

Studies of surgical versus conservative treatment in mild carpal tunnel syndrome have not been done and it is still unclear whether or not surgical treatment is better than conservative treatment.

The aim of this study is to research has surgery better outcome in mild CTS than conservative treatment. Patient satisfactory, clinical and electrophysiologic outcomes, direct and indirect costs will be evaluated.
