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

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

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).

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.
