Summary
The buccinator muscle mucosal flap is a versatile surgical technique for reconstructing oral defects. This flap provides robust vascularity, ensuring successful outcomes in various reconstructive procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Anatomy
Background:
- The buccinator muscle mucosal flap has been utilized since 1984 for diverse oral reconstructions.
- Its application includes mucosal defects post-tumor resection, mandibular osteomyelitis, and cleft palate pathologies.
Purpose of the Study:
- To anatomically evaluate the buccinator muscle's vascular supply and innervation.
- To assess the clinical efficacy of the buccinator muscle mucosal flap in reconstructive surgery.
Main Methods:
- Cadaveric dissection of 14 facial regions to identify the buccal artery and nerve.
- Clinical case review of 38 patients undergoing reconstruction with the buccinator flap.
Main Results:
- The buccal artery confirmed as the major arterial pedicle, closely associated with the buccal nerve.
- Rich venous drainage enhances the flap's vascularity, supporting buccal mucosa.
- Successful reconstruction in 38 patients, with minor complications (3 small fistulas) attributed to technical errors.
Conclusions:
- The buccinator muscle mucosal flap offers reliable vascularization for oral reconstructions.
- Its application is effective for cleft palate repair, fistulas, osteomyelitis, and post-tumor resection defects.
- Meticulous surgical technique is crucial to minimize complications.
