Background: In carpal tunnel syndrome (CTS) surgery, standard incisions to release the median nerve often leave scars that can cause cosmetic concerns, such as hypertrophic scarring or wrist flexion contracture. Previous studies have explored the benefits of mattress sutures in various surgical contexts, such as meniscus and rotator cuff ruptures.
Objectives: The present study compared the scars of single interrupted and horizontal mattress sutures in median nerve open surgery.
Methods: This randomized controlled trial included 60 hands with CTS treated at Rasoul-Akram, Kasra, and Moheb-Kosar hospitals, Tehran, Iran from September 2020 to October 2021. Patients were randomly assigned to two groups: Group 1 (30 hands) received single interrupted sutures, and group 2 (30 hands) received horizontal mattress sutures. Scar characteristics, including height, width, and color, were assessed six months after surgery.
Results: The sample comprised 84.3% female patients, with a mean age of 59.75±11.54 years. The right hand was involved in 61.6% of cases. No significant preoperative demographic differences were noted between the groups (P>0.05). Six months after the surgery, the horizontal mattress group had significantly lower scar widths (2.17±0.13 cm, P=0.012) and heights (P=0.021) than the single interrupted group. No significant difference was found in hyperpigmentation (P=0.098).
Conclusion: Horizontal mattress sutures resulted in significantly smaller and less noticeable scars than single interrupted sutures in median nerve release surgery. This technique may offer fewer complications and better cosmetic outcomes for CTS patients.
