From the Guidelines

For a lip laceration, the treatment plan should prioritize meticulous repair to minimize scarring and functional impairment, with primary wound closure recommended for wounds to the face, including the lip, as stated in the guidelines by the Infectious Diseases Society of America 1. The approach involves:

  • Cleaning the wound with sterile saline or mild antiseptic solution
  • Careful examination to assess depth and involvement of structures like the vermilion border
  • Small, superficial lacerations can be managed with tissue adhesive or steri-strips
  • Deeper lacerations require suturing with fine absorbable sutures (5-0 or 6-0 Vicryl) for muscle layers and non-absorbable sutures (6-0 nylon or polypropylene) for skin closure, with special attention to precisely aligning the vermilion border
  • Prophylactic antibiotics (amoxicillin-clavulanate 875/125 mg twice daily for 5-7 days) are recommended for contaminated wounds or those involving the oral mucosa, as general principles of wound management suggest 1
  • Pain management includes acetaminophen or ibuprofen as needed
  • Patients should maintain good oral hygiene, rinse with diluted antiseptic mouthwash after meals, eat soft foods, avoid lip movement when possible, and return for suture removal in 5-7 days
  • Tetanus prophylaxis should be administered if the patient's immunization status is outdated This approach is supported by general principles of wound care and the importance of cosmetic and functional outcomes in lip lacerations, although specific studies on lip lacerations may not always provide direct guidance on every aspect of management 1.

From the FDA Drug Label

Directions adults and children 2 years of age and older: clean the affected area apply a small amount of this product (an amount equal to the surface area of the tip of a finger) on the area 1 to 3 times daily may be covered with a sterile bandage children under 2 years of age: ask a doctor

The plan for a lip laceration may include cleaning the affected area and applying a small amount of bacitracin ointment (1 to 3 times daily) 2. It is also recommended to cover the area with a sterile bandage. For children under 2 years of age, it is advised to consult a doctor 2.

From the Research

Lip Laceration Plan

Lip lacerations require careful management to achieve a good cosmetic outcome, especially when the vermilion border is involved 3. The goals of managing lip injury include restoring function and esthetics 4.

Key Considerations

  • Lip anatomy: lips consist of 3 layers: skin, muscle, and oral mucosa 3
  • Vermilion border repair: requires preciseness for a good cosmetic outcome, especially when greater than 25% of the lip is involved 3
  • Anesthetic considerations: infraorbital and mental nerve blocks can provide lip anesthesia without distorting crucial aesthetic landmarks 5
  • Antibiotic prophylaxis: usually indicated in perioral injuries due to wound contamination with saliva 5

Management Techniques

  • Three-layered closure for full-thickness lip lacerations 5
  • Advanced management techniques for complex lacerations, such as those involving the fingertip, ear, nose, lip, tongue, and eyelid 6
  • Reconstructive options for large perioral defects, including primary closure, cross-lip flaps, and local tissue transfer 5
  • Lip shave technique for disorders of the vermilion border, involving full-thickness excision of the damaged vermilion and reconstruction with an advancement labial mucosal flap 7

Postoperative Care

  • Wound care and follow-up to monitor for complications, such as infection or hypertrophic scarring 5
  • Use of silicone elastomer sheeting and intralesional steroid injections for the treatment of hypertrophic scars on the lips 5
