Pedicle Orientation in Free-Flap Microvascular Maxillofacial Reconstruction

Area of Science:

• Oral and Maxillofacial Surgery
• Plastic Surgery
• Reconstructive Surgery

Background:

• Maxillary defects from cancer or trauma present reconstructive challenges.
• Oral-nasal and oral-antral fistulas often require complex surgical repair.
• Free fibula microvascular osteocutaneous flaps are a primary method for maxillary reconstruction.

Purpose of the Study:

• To describe a specific surgical technique for optimizing free fibula flap pedicle positioning in maxillary reconstruction.
• To improve flap viability and reduce complications associated with microvascular anastomosis.

Main Methods:

• Detailed surgical description of pedicle positioning within the maxilla and neck.
• Anatomic alterations to facilitate optimal flap inset and vascular flow.
• Focus on preventing vascular compromise, clot formation, and venous congestion.

Main Results:

• The described technique aims to enhance the success rate of microvascular anastomosis.
• Improved pedicle positioning is expected to reduce flap failure due to vascular compromise.
• Provides a clear surgical guide for a well-established reconstructive procedure.

Conclusions:

• Optimizing pedicle positioning is critical for successful free fibula flap reconstruction of the maxilla.
• This technique note addresses a gap in the detailed description of flap inset for maxillary reconstruction.
• The described method offers a strategy to improve outcomes in complex oral and maxillofacial reconstructions.
