Using state-of-the-art morphometric techniques, this report provides a detailed and hierarchical description of the features present in CH-related asymmetric mandibles and offers new knowledge for the surgical treatment of CH.{\textless}br{\textgreater}Materials and Methods{\textless}br{\textgreater}Sixty patients were included in the sample. Thirty had CH-related asymmetric mandibles and the other 30 had clinically symmetric mandibles. Twenty-eight 3-dimensional landmarks were placed on computed tomographically based reconstructions of each participant{\textquotesingle}s mandible and analyzed using geometric morphometric analysis for the quantitative and qualitative comparison of their morphologic features.{\textless}br{\textgreater}Results{\textless}br{\textgreater}All 60 participants exhibited asymmetry. However, those with CH exhibited a broad range of shapes and even shared several morphologic features with the controls. Mainly the ramus and then the body were the main contributors of the differences between groups.{\textless}br{\textgreater}Conclusions{\textless}br{\textgreater}There is considerable overlap of anatomic features characterizing symmetric and asymmetric mandibles; based on shape alone, the 2 groups can be easily misclassified. The ramus and body of the affected side in CH-related asymmetric mandibles were the main contributors to asymmetry of the structure. The chin, a usual diagnostic structure, did not greatly contribute to the structural asymmetry of the mandible.}}, journal = {{Journal of Oral and Maxillofacial Surgery}}, volume = {77}, number = {5}, pages = {1056--1067}, }
