When Sutures (stitches) are Needed

• Any cut that is split open or gaping probably needs sutures.
• Cuts longer than ½ inch (12 mm) usually need sutures.
• On the face, cuts longer than ¼ inch (6 mm) need closure with sutures or skin glue.
• Any open wound that may need sutures should be checked and closed as soon as possible. There is no cutoff, however, for treating open wounds to prevent wound infections.
