Summary
This study provides crucial anatomical data for using the reversed submental island flap in facial defect reconstruction. Findings confirm the flap
Area of Science:
- Anatomy
- Surgical Reconstruction
- Head and Neck Surgery
Context:
- Reconstruction of complex buccal and facial defects presents significant challenges.
- The submental island flap is a potential reconstructive option, but its anatomical basis requires detailed investigation.
Purpose:
- To provide detailed anatomical data for the clinical application of the reversed submental island flap in reconstructing buccal and facial defects.
Summary:
- Dissection of 40 head and neck sides from formalin-fixed and 6 fresh cadavers revealed key measurements of the submental artery and its branches.
- The study documented distances, diameters, and anastomoses of the submental artery, facial artery, and associated nerves and veins.
- Rich anastomoses were observed between facial arteries and other vessels, and detailed descriptions of nerve and vein pathways were recorded.
Impact:
- The findings support the anatomical feasibility of using a pedicled submental reversed island flap for buccal and facial defect reconstruction.
- This data can guide surgeons in optimizing flap design and surgical technique for improved patient outcomes.
- Establishes the reversing point of the flap at or inferior to the cheilion plane for successful reconstruction.
