Defect subdivision as a technique to repair defects following Mohs surgery

Defects following Mohs surgery that cannot be closed primarily or with single flaps may often be reconstructed using the concept of defect subdivision. This involves mentally fragmenting the wound into smaller portions. Each subsegment is reconstructed with a small transposition flap. The closures of the donor sites of these flaps are designed so that each taps into a separate and distinct area of skin laxity. In this way efficient and optimal use is made of available matching regional skin for reconstruction.
