The stitch removal time is not consistent for different surgical sites. Usually, the stitch removal time for the head, face and neck is 4-5 days after surgery, for the trunk is 7-9 days after surgery, and for the extremities is 9-14 days after surgery, and if the surgical site is located near the joint, the stitch removal time can be extended by 2-3 days. The head, face and neck are rich in blood supply and have low suture tension, so the wound heals faster. The trunk includes the abdomen, back, buttocks, and back. These areas take a little longer to remove the sutures because they require more layers of sutures and are more traumatic after surgery. The extremities are less vascular and more active, so the healing time is relatively longer, and the parts near the joints are the most active and have high suture tension, so the stitch removal time is the longest. It should be noted that the stitch removal time for the same site is not invariable, and the stitch removal time is also related to the patient’s physical condition, blood supply to the surgical site, age, and the presence of infection, so do not remove the stitches blindly.
