Background: Carpal tunnel syndrome is one of the most common compression neuropathies in the upper limbs and requires surgery if conservative treatment fails. This article compares the result of regular open incision, mid-palmar mini incision and endoscopic technique in carpal tunnel release. Methods: This is a clinical trial study on 105 patients (10 males, 95 females) within one year, who were surgical candidates. The surgery was done with regular open incision or with mid-palmar small incision. The clinical outcomes were evaluated one week, 4 weeks and 4 months post-surgery. Results: Relief and satisfaction were better in the first month in the endoscopic and mid-palmar mini incision group. All 3 techniques had similar outcomes after 4 months. In the 4-month follow-up, night pain relief, followed by parasthesia relief had the best improvement. Weakness was the symptom with the least improvement. Longer incision cases were associated with more delay to return to work. Conclusion: Carpal tunnel release with endoscopic and mini incision techniques have better early satisfaction rates compared to regular open incision, but no difference is seen between the two groups after four months.
