New Research Spotlight: What Predicts Bone Healing After Fibula Free Flap Mandibular Reconstruction?

Article from China

Mandibular reconstruction with fibula free flap remains one of the most important techniques for restoring form and function following resection. A newly published study in Oral Oncology analyzed 75 patients and 202 osteotomy sites to better understand which factors most influence long-term osseous union.

Interestingly, researchers found that initial osteotomy gap width did not significantly predict long-term healing. Instead, stronger predictors included vascular health, osteotomy location, fibula morphology, and whether healing occurred between fibula segments or between fibula and native mandible.

Fibula-to-fibula interfaces demonstrated stronger healing outcomes, while symphyseal regions outperformed body and angle regions. The study also found that vascular comorbidities and alcohol use were associated with poorer union outcomes.

What Caught Our Attention

These findings may help refine surgical planning, fixation strategies, and risk assessment in mandibular reconstruction cases. The research also reinforces the growing value of 3D-assisted planning in achieving precise alignment for complex reconstructions.
