    Abstract:
    PURPOSE: Facial asymmetry associated with unilateral condylar hyperplasia can benefit from condylectomy, which aims to arrest the pathologic condylar growth and restore an appropriate posterior height. However, there are several cases in which condylar hyperplasia is combined with various dentofacial deformities, for which joint surgery has to be accompanied by concomitant orthognathic surgery. The literature is relatively poor of examples in which virtual planning for orthognathic surgery includes the evaluation of condylectomy, which is often manually performed. The aim of this study was to present and discuss a workflow for 1-stage computer-guided customized management of skeletal asymmetry by simultaneous condylectomy and orthognathic surgery. MATERIALS AND METHODS: Five patients were enrolled in this study from 2018 to 2019. All patients underwent combined virtual planning of orthognathic surgery and condylectomy. Virtual surgery was translated into real surgical coordinates using patient-specific surgical guides and custom-designed osteosynthesis plates. RESULTS: All surgical procedures were uneventful, and in all patients, virtual planning was successfully brought into the operating room with high accuracy, as confirmed by superimposition analyses. Symmetrization of the face and achievement of correct occlusion were observed in all cases. CONCLUSIONS: The presented protocol is a reliable solution for the combined planning of orthognathic surgery and condylectomy. Virtual planning, surgical guides, and custom-designed plates allow computerized simulations to be replicated in the real patient.
