Virtual Surgical Planning Systems in Mandibular Reconstruction (VP3D)

March 11, 2019 updated by: Hospices Civils de Lyon

Evaluation of Virtual Surgical Planning Systems and Customized Devices in Fibula Free Flap Mandibular Recontruction

The purpose of this study was to evaluate the accuracy of virtual planning using customized surgical devices (VP3D) in fibula free flap mandibular reconstruction. Virtual planning was compared to postoperative scans using cephalometric and three-dimensional (3D) measurements. Operative times of both VP3D and conventional surgery groups were compared.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Conventional surgery
Classical surgery for mandibular reconstruction with fibula free flap
Procedure: Conventional surgery
Classical surgery for mandibular reconstruction with fibula free flap
Virtual planning
Fibula free flap in mandibular reconstruction using preoperative virtual planning, cutting guides and osteosynthesis plates. Preoperative modeling was conducted by obtaining scans of patient maxillofacial skeleton and angioscans of the lower extremities. The planning phase was then carried out by the surgeon and the engineer (from MATERIALISE, Leuven, Belgium) so as to define the clinical and technical parameters of the reconstruction. This stage consisted of discussing and determining osteotomy lines, donor side, anastomosis site, and overall reconstruction contour. Resection was decided by the surgeon. 3D modeling and the manufacture of cutting guides and customized osteosynthesis plates were then undertaken

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Comparison of the cephalometrics measurements between the virtual model and postoperative outcomes
Time Frame: Six months after surgery

The virtual model obtained using preoperative surgical planning will be compared with postoperative outcomes derived from facial bone scans conducted on all VP3D group patients 6 months after surgery (MIMICS INNOVATION suite 2.1 software, MATERIALISE, Leuven, Belgium).

The cephalometrics measurements (in mm) between the virtual model and postoperative outcomes will be compared.
Six months after surgery
