Although the traditional super-tension-reducing suture method can improve incision scars, there are problems such as exposure of the needle entry and exit points, which may cause adverse reactions such as pigmentation and scar hyperplasia.Methods: This prospective study proposes a new super-tension-reducing suture method-distal complete dermal undermining super-tension-reducing suture, which aims to reduce scar hyperplasia by reducing the needle entry and exit points on the incision. This method inserts the needle subcutaneously, undermines 1 cm in the dermis, and then withdraws the needle from the subcutaneous layer, which effectively avoids suture exposure and incision edge irritation. At the same time, by increasing the stress-bearing site, the maintenance time of the super-tension-reducing effect is prolonged.Results: This study was clinically applied to 50 patients with oral and maxillofacial surgery. The results showed that the observation group was superior to the control group in terms of scar score, pigmentation, centipede-foot scars and delayed incision healing, indicating that this new suture technique can effectively reduce scar hyperplasia and improve incision healing.Conclusion: This method provides a new technical option for surgical wound healing and has good clinical application prospects.Keywords: tension-reducing suture, scar formation, dermal suture, aesthetic outcomes, flap donor site, subcuticular suture, surgical scar prevention
