'

Direct skin flaps are a type of wound closure used to cover a wound in a patient's skin. This procedure requires only a local anesthetic and can be used to cover a variety of skin wounds.

Direct skin flaps are composed of the patient's own skin and tissue that is shifted from an adjacent area to cover the wound. These flaps can be very thin and may even contain skin just a single layer thick. The adjacent donor area is usually carefully planned and marked on the patient's body prior to performing the surgery.

The flap is lifted and moved to the wound area under local anesthesia. Surgeons use sutures to attach the flap to the skin around the wound. The blood flow is relatively undisturbed because the donor tissue is located close to the wound area. This helps to reduce the risk of tissue loss or necrosis in the flap area.

Direct skin flaps are commonly used for wound closure on the face and other areas that have few surrounding donor sites. In addition, they are often used to close large wounds or skin grafts that require more coverage than a single layer of skin can provide.

Direct skin flaps can be used as a primary closure technique, or as a secondary closure technique when other techniques, such as a split-thickness skin grafts, are not suitable. This technique can also be used to create a permanent covering of the wound and reduce scarring.
