Hello, the common complication of skin grafting is skin flap necrosis.

Guiding opinions:

There are many reasons for skin flap necrosis, including improper postoperative care and infection. If there are many necrotic flaps, the necrotic flaps should be removed and the surgical dressing should be replaced. If the necrotic flap is small, it can be left untreated, especially if the flap has self-healing ability. Generally, there will be scar sequelae after surgery.
