Muscle Coverage With Fibula Flaps Using Fibrin Glue and a Polyglycolic Acid Sheet: A Six-Patient Case Series

Area of Science:

• Oral and Maxillofacial Surgery
• Reconstructive Surgery
• Biomaterials Science

Background:

• Segmental mandibular defects often require bone grafting for stabilization.
• Current reconstruction methods aim to restore function and aesthetics.
• Novel techniques are explored to improve outcomes and minimize complications.

Purpose of the Study:

• To assess the efficacy of fibular bone grafting combined with the flexor hallucis longus (FHL) muscle.
• To evaluate a modified mucosal coverage technique using fibrin glue and polyglycolic acid (MCFP) for mandibular reconstruction.
• To analyze postsurgical complications and functional outcomes.

Main Methods:

• Six patients with segmental mandibular defects underwent reconstruction.
• Fibular bone graft with FHL muscle was utilized.
• Oral mucosal defects were covered using fibrin glue and polyglycolic acid (MCFP).

Main Results:

• Complete oral wound epithelialization occurred within 1-2 months.
• Postsurgical complications included skin paddle necrosis (2 patients) and neck wound healing issues (3 patients).
• All patients achieved good masticatory function and stable denture support.

Conclusions:

• The fibular bone graft with FHL muscle and MCFP technique offers a viable option for mandibular reconstruction.
• This method provides durable mucosal coverage, aiding denture stability.
• While complications can occur, they are manageable, and the technique shows potential for small intraoral defects.
