The location of a laceration dictates how long sutures should remain in place. Stitches in the face usually need to remain in place for five days, while sutures elsewhere on the body may need to stay in place for up to 10 days, according to MedicineNet.
Sutures on the face usually need to be left in place a shorter period of time because the blood supply is optimal in the facial region so healing is heightened. The potential for sutures to cause scarring is also a consideration in determining removal times, and sutures can be left in place longer in situations where the risk of scarring is minimal. Sutures are also left in place longer when there is risk of stress on the laceration, such as when it is on an elbow, knee or other location, according to MedicineNet.
