Assessment of Facial Symmetry Following Fibula Free Flap Fixated in a Prosthetically Favorable Position Versus the Inferior Border Position for Mandibular Reconstruction

The study aims to evaluate facial symmetry outcomes after mandibular reconstruction using fibula free flaps, comparing two fixation techniques: the prosthetically favorable position (alveolar level) and the conventional position (inferior border level).

Design:

A randomized controlled trial with parallel groups and a 1:1 allocation ratio. The study will assess facial symmetry and patient satisfaction over 12 months post-surgery.

Population:

Patients requiring mandibular reconstruction due to conditions like tumors, trauma, or osteomyelitis, with mandibular defects greater than 9 cm.

Interventions:

Group 1: Fibula free flap fixated at the alveolar level (prosthetically favorable position).

Group 2: Fibula free flap fixated at the inferior border level (conventional position).

Setting:

Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Cairo University.

Duration:

Follow-up over 12 months post-surgery, with key data collection points at baseline, 3 days, 1 week, 1 month, 6 months, and 12 months postoperatively.

Inclusion criteria

• Patient who requires mandibular resection due to tumor, trauma, osteomyelitis or osteoradionecrosis.
• Patient with Mandibular defect >9 cm.

Exclusion criteria

• Patients with systemic condition counteracting with the surgical procedure.
