Free tissue transfer is a surgical technique used to move tissue from one part of the body to another while maintaining its blood supply. This method is often employed in reconstructive surgery to repair defects caused by trauma, cancer, or congenital conditions. Surgeons carefully detach a section of skin, muscle, or other tissue along with its blood vessels and then reattach it at the target site. The procedure typically involves microsurgery, where specialized instruments are used to connect the blood vessels of the transferred tissue to those at the recipient site. Successful free tissue transfer can significantly improve healing and aesthetic outcomes, making it a valuable option in the field of reconstructive surgery.
