A Novel Method for Quantitative Three-Dimensional Analysis of Zygomatico-Maxillary Complex Symmetry.

ABSTRACT:

Objective

To develop a reliable and accurate method to quantify the symmetry of the zygomaticomaxillary complex (ZMC).

Methods

Virtual three-dimensional models were created from 53 computed-tomography scans: 15 healthy cases without maxillofacial disorders and 38 patients with ZMC fractures requiring surgical treatment.Asymmetry of the ZMC was measured using a mirroring and surface-based matching technique that uses the anterior cranial fossa as reference to determine the symmetrical position of the ZMC. The measure for ZMC asymmetry was defined as mean surface distance (MSD) between the ZMC-surface and the symmetrical position.Reliability of the method was tested in the 15 healthy cases. Inter- and intra-observer correlation coefficients (CC) and variabilities were assessed
