The purpose of skin grafting is to promote wound healing, reduce scarring, and restore the functionality and appearance of the affected area.

There are two main types of skin grafts:

1. Autograft: In an autograft, the skin is taken from a healthy area of the patient’s own body (usually from the thigh, upper arm, or buttocks) and transplanted to the damaged area. Autografts are the most common type of skin graft and tend to have a higher success rate because the body is less likely to reject its own tissue.

2. Allograft or Homograft: In an allograft, the skin is taken from another human donor (usually a deceased person) and used as a temporary covering for the wound. Allografts act as a biological dressing, providing a temporary barrier while the body heals. They are often used in cases where the patient’s own skin is not available or when a large amount of skin is needed quickly.

The skin grafting procedure involves removing the healthy skin from the donor site, preparing the wound area for graft placement, and then carefully applying the graft to the recipient site. The graft is secured with stitches, staples, adhesive, or special dressings. Over time, new blood vessels grow into the graft, and it becomes a permanent part of the recipient site.
