Abstract:Wound healing involves dynamic stages such as inffammation, proliferation and remodeling, with differences in the source and intensity of tension at each stage. If the incision is in a state of abnormal traction for a long time during healing, it can lead to prolonged inffammatory phase, imbalanced collagen deposition, and promote scar widening, elevation or even contracture, thereby affecting local function and appearance. Due to the time-dependent and multi-factor superimposed characteristics of the stress on the wound edge, a single tension reduction method is often difffcult to achieve full coverage in terms of time and mechanics. Therefore, the concept of comprehensive intervention centered on combined tension reduction has attracted increasing attention. This paper reviews various tension reduction measures from a mechanism-based perspective, including incision design, precise intraoperative suturing and suture selection, postoperative external ffxation, and the auxiliary use of botulinum toxin type A to reduce muscle traction. Focusing on the stress characteristics of typical high-tension areas such as the trunk and face, this paper summarizes the combined application strategies for selecting and adjusting tension reduction intensity based on the incision site and individual risk factors, and emphasizes the full-course management of wound edge tension before, during and after surgery, in order to provide clinical reference for the prevention and comprehensive treatment of pathological scars related to tension incisions.
