Dehydrated human amnion/chorion membrane allograft as an aid for wound healing in patients with full-thickness scalp defects after Mohs micrographic surgery

Large surgical defects after Mohs micrographic surgeries (MMS) often require rotation or advancement flaps, skin grafts, or delayed reconstruction after use of tissue expanders. For patients with limited tissue redundancy, wounds may also heal by secondary intention. Elderly patients undergoing MMS with full-thickness defects exposing bone pose a unique set of healing barriers, such as immunosuppression, increased infection risk, poor tolerance to bone chiseling for exposing pinpoint bleeding, and difficulty in reaching wounds to apply dressings successfully.
