Mandibular condyle reconstruction with fibula free-tissue transfer

Area of Science:

• Oral and Maxillofacial Surgery
• Reconstructive Surgery
• Oncology

Background:

• Mandibular condyle defects often result from trauma, tumor resection, or infection.
• Reconstruction aims to restore function (mastication, speech) and aesthetics.
• Vascularized free fibula flaps are a common option for large bony defect reconstruction.

Purpose of the Study:

• To evaluate functional and cosmetic outcomes of mandibular condyle reconstruction.
• To assess the efficacy of direct placement of a vascularized free fibula.
• To analyze outcomes following hemimandibulectomy and condyle resection.

Main Methods:

• Retrospective review of patients undergoing hemimandibulectomy and condyle resection with immediate reconstruction.
• Study period: November 1, 2005, to January 31, 2007, at Mayo Clinic.
• Focus on cases with direct placement of a vascularized free fibula into the condylar fossa.

Main Results:

• Seven male patients (ages 32-61) were included; six had malignancy, one had osteomyelitis.
• Six patients achieved good/excellent occlusion at 6 months; one had an open bite but could masticate.
• Satisfactory cosmesis and intelligible speech were maintained in all patients.

Conclusions:

• Direct free fibula transfer to the condylar fossa is a viable technique for mandibular reconstruction.
• Aggressive physiotherapy is crucial for optimizing functional outcomes post-reconstruction.
• This method yields acceptable functional and cosmetic results for mandibulectomy-condylectomy defects.
