Summary
Reconstructing large lower lip defects is challenging. A novel technique using a zygomaticus major muscle sling, nasolabial flap, and facial artery flap successfully restored function and aesthetics in an 80% lower lip defect.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
Background:
- Lower lip defects pose significant reconstructive challenges, impacting aesthetics and function.
- Current surgical techniques often result in deformity and morbidity.
- Restoration of oral competence, speech, and lip contour are primary goals.
Observation:
- A case report details a new technique for an 80% lower lip defect.
- The reconstruction utilized an ipsilateral split zygomaticus major muscle sling, nasolabial flap, and facial artery musculomucosal flap.
- The technique preserved oral commissure and lip height/length, avoiding iatrogenic microstomia.
Findings:
- The described technique achieved good oral competence and speech articulation.
- Excellent aesthetic outcomes were reported.
- Normal zygomaticus muscle function was maintained post-reconstruction.
Implications:
- This novel technique offers a promising solution for complex lower lip reconstructions.
- It may be a valuable option for reconstructive surgeons managing extensive lower lip defects.
- Further application could improve patient outcomes and reduce reconstructive morbidity.
