Summary
Reconstructing complete bilateral maxillary defects using micro-vascular free flaps is a safe and reliable procedure. This study shows high flap survival rates and successful patient recovery, enabling soft diet resumption.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Reconstructive Surgery
Background:
- Complete bilateral maxillary defects (CBMDs) present significant reconstructive challenges due to extensive bone and soft tissue loss.
- Various micro-vascular free flaps are utilized for reconstruction, each with specific advantages.
Purpose of the Study:
- To evaluate the surgical outcomes of micro-vascular free flap reconstructions for CBMDs.
- To discuss and compare different reconstruction options for these complex defects.
Main Methods:
- A retrospective case series of 46 consecutive patients with CBMDs undergoing micro-vascular free flap reconstruction.
- Analysis of flap types used, including free fibula, anterolateral thigh, rectus abdominis, radial forearm, and composite flaps.
- Review of patient outcomes, including flap survival and functional recovery.
Main Results:
- Free fibula flap was the most common method (n=26), used across all defect types.
- A high overall flap survival rate of 44 out of 46 flaps was observed.
- All patients were able to resume a soft diet postoperatively, indicating successful functional restoration.
Conclusions:
- Micro-vascular free flap reconstruction is a safe and reliable method for addressing CBMDs.
- The study highlights the effectiveness of various free flap options in achieving successful outcomes for extensive maxillary defects.
