Summary
This study evaluated 20 mandibular reconstructions for osteoradionecrosis after head and neck cancer radiotherapy. Free flap reconstructions achieved an 88% success rate, demonstrating their effectiveness in treating this serious complication.
Area of Science:
- Oral and Maxillofacial Surgery
- Oncology
- Reconstructive Surgery
Background:
- Osteoradionecrosis (ORN) of the mandible is a severe complication after radiotherapy for head and neck cancers.
- Reconstruction of mandibular defects is crucial for restoring function and quality of life.
Purpose of the Study:
- To evaluate the success rates of various reconstructive methods for mandibular defects caused by ORN.
- To identify factors influencing successful reconstruction outcomes.
Main Methods:
- Retrospective analysis of 20 patients with ORN-related mandibular defects.
- Utilized various osseocutaneous free flaps (upper lateral arm, radial forearm, iliac crest, fibula) and fixation methods (condylar prosthesis, reconstruction plate, bridging plate).
Main Results:
- Overall success rate of 75% (15 out of 20 reconstructions).
- Free grafts alone achieved an 88% success rate (15 out of 17).
- Fibular grafts and alloplastic reconstructions showed lower success rates due to complications like exposure and infection.
Conclusions:
- Osseocutaneous free flaps are a successful option for reconstructing mandibular defects due to ORN.
- Free grafts demonstrate a high success rate, outperforming alloplastic options in this cohort.
- Careful patient selection and surgical technique are vital to minimize complications and optimize outcomes.
