Reconstruction of Extensive Maxillary Defects Using Flow-Through Fibula Free Flap With Anterolateral Thigh Free Flap.

BACKGROUND: The maxillary defects left unreconstructed or inadequately reconstructed often result in significant functional and esthetic impairments. Adequate reconstruction of extensive maxillary defects requires a sufficient volume of hard and soft tissues. METHODS: A 48-year-old male presenting bilateral extensive maxillary defects underwent secondary reconstruction with a flow-through fibula free flap in combination with an anterolateral thigh free flap. RESULTS: The use of flow-through technique allowed minimizing the problem of limited recipient vessels and the length of free flap vascular pedicle usually encountered in secondary reconstruction. The bilateral maxillary defects were successfully reconstructed, and the postoperative outcomes were uneventful. The patient was satisfied with the treatment outcomes. He is being followed up and was referred to the implantology department for the placement of osseointegrated dental implants. CONCLUSIONS: The flow-through fibula free flap, in combination with the anterolateral thigh free flap, was found reliable and feasible for this case of secondary reconstruction of bilateral maxillary defects. This technique has provided satisfactory functional and esthetic outcomes and effectively improved the patient's self-esteem.
