Accuracy of computer-assisted surgery in mandibular reconstruction: A postoperative evaluation guideline

Abstract

Comparing accuracy results for mandibular reconstructions using computer-assisted surgery (CAS) is limited due to heterogeneity in image acquisition, extent of mandibular resection, and evaluation methodologies between studies. We propose a practical, feasible and reproducible guideline for standardizing evaluation methods to allow valid comparisons of postoperative results and facilitate meta-analyses in the future. It offers a guide to imaging, data comparison, volume assessment of 3-dimensional models, classification of defects, and it also contains a quantitative accuracy evaluation method.
