Reconstructive microvascular surgery is a specialized surgical technique used to reconstruct various parts of the body, particularly those affected by trauma, cancer, or congenital abnormalities. It involves the transfer of tissue from one part of the body to another using small blood vessels, typically less than 3 to 4 millimeters in diameter, known as microvessels. These microvessels are carefully reconnected to blood vessels in the recipient site under a microscope, allowing for the transfer of tissue while maintaining blood flow. Common applications of reconstructive microvascular surgery include breast reconstruction after mastectomy, reconstruction of the head and neck following cancer removal, limb salvage procedures after trauma or tumor resection, and reconstruction of the jaw and face. This precise surgical technique enables the restoration of form and function to affected areas, often resulting in improved quality of life for patients.
