Novel Reconstruction Method Using the Double-Arm Vascularized Fibula Flap and TriLock Bridging Plate System for...

Area of Science:

• Oral and Maxillofacial Surgery
• Plastic and Reconstructive Surgery
• Biomedical Engineering

Background:

• Segmental mandibulectomy poses challenges for reconstructing the anterior mandibular ramus.
• Conventional reconstruction methods often result in unstable fixation and suboptimal positioning of bone grafts.
• Deformity and functional deficits, such as buccal depression and impaired mastication, can occur without adequate reconstruction.

Purpose of the Study:

• To develop and evaluate a novel reconstruction technique for the anterior border of the mandibular ramus following segmental mandibulectomy.
• To improve the stability and positioning of vascularized fibular flaps in mandibular reconstruction.
• To prevent complications like buccal depression and masticatory dysfunction.

Main Methods:

• Development of a novel reconstruction method utilizing a double-arm vascularized fibular flap.
• Application of the TriLock Bridging Plate System (Medartis AG) for stable fixation of the reconstructed bone segment.
• Comparison of the novel method's fixation stability with conventional reconstruction plates.

Main Results:

• The TriLock Bridging Plate System provides stable fixation for reconstructed bone at the anterior border of the mandibular ramus.
• The two-arm design of the plate facilitates secure and ideal positioning of the fibular flap.
• This innovation overcomes the limitations of conventional plates requiring single screws or dual plates for stability.

Conclusions:

• The novel reconstruction method using a double-arm vascularized fibular flap and the TriLock Bridging Plate System offers a stable and effective solution for anterior mandibular ramus reconstruction.
• This technique addresses the limitations of conventional methods, enabling precise placement and secure fixation of the graft.
• Improved reconstruction can lead to better functional and aesthetic outcomes for patients undergoing segmental mandibulectomy.
