plastic surgery, surgical repair of congenital or acquired deformities and the restoration of contour to improve the appearance and function of tissue defects. Development of this specialized branch of surgery received impetus from the need to repair gross deformities sustained in World War I World War I, 1914–18, also known as the Great War, conflict, chiefly in Europe, among most of the great Western powers. It was the largest war the world had yet seen.

In addition to correcting a disfigurement, plastic surgery is often needed to restore vital movement and function of tissues that have been destroyed. It is also performed for purely cosmetic purposes, such as improving the shape of a nose, bringing outstanding ears closer to the head, or lifting the skin to erase wrinkles, and the term cosmetic surgery is often used to refer to such surgical procedures.

plastic surgery

Surgery to correct disfigurement, restore function, or improve appearance. It may involve reshaping or moving tissues to fill a depression, cover a wound, or improve appearance. Cosmetic surgery solely to improve appearance is not the main focus of plastic surgery. It is utilized after disfigurement by burns or tumour removal or for reconstructive work, and it may involve hiding incisions in skin folds or using buried sutures to hold wounds closed. Reconstructive plastic surgery corrects severe functional impairments, fixes physical abnormalities, and compensates for tissue lost to trauma or surgery. Microsurgery and computerized diagnostic imaging techniques have revolutionized the field.
