Skin grafting is a key procedure for repairing skin defects, with the success depending on the right graft choice, donor site management, and aftercare.

High amphiregulin in the skin is a bad sign for acute graft-versus-host disease.

The traditional method of estimating skin graft success by looking is generally reliable but less so for inexperienced observers and in certain wound conditions.

The document concludes that rib-sparing techniques in breast reconstruction have limited benefits, sentinel lymph node biopsy is needed for desmoplastic melanoma, certain hair preservation methods improve graft survival, partial turbinectomy effectively reduces nasal obstruction, nipple shields with irrigation may reduce capsular contracture, and thicker malignant melanomas have a higher risk of non-skin cancers.
