Summary
A new bilateral pedicled mucosal sliding advancement flap (BPM-SAF) offers a single-stage solution for moderate lower lip defects. This technique successfully reconstructed defects with excellent functional and aesthetic outcomes, minimizing complications.
Area of Science:
- Plastic Surgery
- Oral and Maxillofacial Surgery
- Reconstructive Surgery
Background:
- Reconstructing moderate lower lip vermilion defects presents significant challenges.
- Existing methods may have limitations in achieving optimal functional and aesthetic results.
Purpose of the Study:
- To introduce and evaluate a novel single-stage technique, the bilateral pedicled mucosal sliding advancement flap (BPM-SAF), for lower lip vermilion reconstruction.
- To assess the safety, efficacy, and outcomes of the BPM-SAF technique.
Main Methods:
- A retrospective case series involving 10 subjects who underwent BPM-SAF reconstruction following tumor resection.
- The technique involves advancing adjacent mucosa laterally via a horizontal relaxing incision above the vestibular sulcus.
Main Results:
- Complete survival of all mucosal flaps was observed over a mean follow-up of 13.3 months.
- Donor sites healed without infection, significant scar contracture, or microstomia.
- High patient satisfaction with postoperative oral competence and aesthetic appearance was reported.
Conclusions:
- The BPM-SAF is a practical, single-stage reconstructive option for moderate partial-thickness lower lip vermilion defects.
- The technique is suitable when lip height, cutaneous tissue, oral commissures are preserved, and adequate residual mucosa is available.
- BPM-SAF facilitates functional and aesthetic restoration with minimized donor site morbidity by preserving bilateral vascular pedicles.
