Misplaced, elongated or split piercings cannot be simply sewn together, as the skin will not heal without a ridge, dimple or bump. Thus, the edges must be freshened by cutting out the piercing, usually by means of a Z-plasty to minimize the scarring and strengthen the repair, and the wounds sewn together with very fine sutures.
