From the Research
Sutures from a lip laceration should typically be removed after 5 to 7 days. For facial wounds including the lip, earlier suture removal is preferred to minimize scarring, as the face has excellent blood supply and heals more quickly than other body areas. Mucosal (inside the mouth) sutures may be removed slightly earlier, around 3 to 5 days, while external lip sutures should remain for the full 5 to 7 days. After suture removal, the wound should be protected from excessive tension for several more weeks as it continues to gain strength. Signs that indicate appropriate timing for removal include good approximation of wound edges, minimal redness, and no signs of infection such as increasing pain, swelling, or discharge. If dissolvable sutures were used, they will typically disappear on their own within 1 to 2 weeks, though this varies by suture material. Following suture removal, the healed wound should be protected from sun exposure for several months and may benefit from silicone-based scar treatments to optimize cosmetic outcomes. If there are any signs of infection or abnormal healing, medical attention should be sought before attempting suture removal.
Key Considerations
- The timing of suture removal is crucial to prevent infection and promote healing 1.
- Facial wounds, including lip lacerations, have a lower risk of infection due to excellent blood supply 2.
- Mucosal sutures can be removed earlier than external lip sutures 3.
- Dissolvable sutures will disappear on their own within 1 to 2 weeks 4.
- Protection from sun exposure and silicone-based scar treatments can optimize cosmetic outcomes 5.
