undermining

Full Definition

Undermining is a surgical technique that involves separating tissue layers, typically between the dermis and subcutaneous tissue or between tissue planes, to create mobility for wound closure or tissue repositioning. This technique is commonly used in skin cancer reconstruction, scar revision, and aesthetic procedures to reduce tension on wound edges and achieve optimal cosmetic results. The extent and depth of undermining must be carefully planned to preserve blood supply while achieving the desired tissue mobility.
