A modified method for a customized harvest of fibula free flap in maxillofacial reconstruction

Résumé

Mandibular reconstruction using computer-aided design/computer-aided manufacturing cutting guides is currently a common procedure. However, inaccurate positioning of the cutting guide onto the fibular bone may result in osteosynthesis difficulties or imprecision in the reconstruction. A novel way to improve the stability of the cutting guides may be to add pillars in order for them to be suspended from the fibula, avoiding soft tissues interactions. We present the case of a 39-year-old male who needed mandibular reconstruction after a self-inflicted ballistic injury. We designed a customized cutting guide which included a set of 8 pillars allowing a suspension of the cutting guide 8 millimeters above the bone level. The pillars were perpendicular to one another, and allowed the operator to screw the cutting guide to the bone. The orthogonal position of the pillars enabled real stability during the osteotomies. In the operator experience, the length of the pillars was too important, and led to incomplete osteotomies, and the whole device was too bulky. However, with adaptations in the size of the pillars and the size of the whole device, this solution could be useful in cutting guide design to avoid impairments due to the soft tissues surrounding the fibula.
