Optimizing Osteotomy Geometries in Posterolateral Mandibulectomies.

ABSTRACT:

Importance

Reconstructive stability after mandibulectomy with osseous autogenous transplant is influenced by masticatory forces and the resulting stress on the titanium plate.

Objective

To determine an optimal geometry of mandibular osteotomy that minimizes undesirable loading of the reconstruction plate.

Design, setting, and participants

In this combined in silico and in vitro basic science study, segmented computed tomography images of an adult male human mandible downloaded from the Visible Human Project were analyzed. Data were collected from July to November 2023.

Exposures

Four posterolateral mandibular resections and bony transplants were modeled following (1) vertical, (2) angled, (3) step, and (4) sagittal osteotomies. Using SOLIDWORKS software, mastic
