Summary
This study details the vascular anatomy of the buccinator muscle, revealing specific arterial branches crucial for designing buccinator musculomucosal island flaps. These flaps offer effective reconstruction for various oral and facial defects.
Area of Science:
- Anatomy
- Vascular Surgery
- Head and Neck Surgery
Background:
- The buccinator muscle's vascular supply is critical for reconstructive surgery.
- Understanding its detailed vascular anatomy aids in flap design.
Purpose of the Study:
- To investigate the vascular anatomy of the buccinator muscle.
- To propose two patterns of buccinator musculomucosal island flaps based on this anatomy.
Main Methods:
- Dissection of fresh cadavers to map the vascular supply of the buccinator muscle.
- Identification of buccal arterial branches and their anastomoses.
- Description of venous drainage patterns.
Main Results:
- Consistent identification of posterior, inferior, and anterior buccal branches of the facial artery supplying the buccinator.
- Two distinct patterns of buccinator musculomucosal neurovascular island flaps were proposed.
- Successful application of these flaps in 12 patients with satisfactory aesthetic and functional outcomes and no flap necrosis.
Conclusions:
- The detailed vascular anatomy of the buccinator muscle supports the creation of versatile musculomucosal island flaps.
- These flaps are reliable for reconstructing defects in the palate, oral cavity, and facial structures.
- The study provides a foundation for utilizing buccinator flaps in head and neck reconstruction.
