Summary
A novel lower lip reconstruction technique uses a nasolabial flap and orbicularis oris muscle transposition. This method also utilizes a split tongue to create intraoral lining and a new lip vermilion for improved function.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Oral and Maxillofacial Surgery
Background:
- Lower lip defects pose significant reconstructive challenges, impacting function and aesthetics.
- Existing techniques may have limitations in restoring both intraoral lining and the vermilion border.
- A need exists for innovative approaches to achieve comprehensive lower lip reconstruction.
Observation:
- A functional variant of lower lip reconstruction was developed.
- The technique involves a nasolabial skin flap.
- Upward transposition of the inferior orbicularis oris muscle was performed in a 'bucket-handle' fashion.
Findings:
- The nasolabial flap provided external coverage.
- Transposed orbicularis oris muscle contributed to lip function and contour.
- A split tongue was ingeniously used to supply both the intraoral lining and a new vermilion border.
Implications:
- This technique offers a viable solution for complex lower lip defects.
- It potentially improves functional outcomes, including speech and oral competence.
- The method highlights the versatility of combined flap and tissue transposition in facial reconstruction.
