In our study we wished to investigate 3D variations in the condylar position in a group of patients who had undergone orthognathic surgery involving the saggital bilateral osteotomy of the mandibular rami, combining the capability of the cone-beam with software able to generate a 3D cephalometry. Ol all parameters considered, only the angulation of the right condyle with respect to the median saggital plane and to a lesser degree, its transversal position, showed any significant variation between pre and postsurgery. For alle the other variables the changes were negligible: less than a millimeter for linear distances or less than a degree for angular mesures. In patients who underwent an osteotomy of the mandibular rami for the correction of a dentofacial dysmorphism , and who didn't present dysfunction of the temporomandibular joints, the manual intraoperator monitoring of the proximal segments of the osteotomy was able to mantain the condyle in the presurgical position.

Abstract

In our study we wished to investigate 3D variations in the condylar position in a group of patients who had undergone orthognathic surgery involving the saggital bilateral osteotomy of the mandibular rami, combining the capability of the cone-beam with software able to generate a 3D cephalometry. Ol all parameters considered, only the angulation of the right condyle with respect to the median saggital plane and to a lesser degree, its transversal position, showed any significant variation between pre and postsurgery. For alle the other variables the changes were negligible: less than a millimeter for linear distances or less than a degree for angular mesures. In patients who underwent an osteotomy of the mandibular rami for the correction of a dentofacial dysmorphism , and who didn't present dysfunction of the temporomandibular joints, the manual intraoperator monitoring of the proximal segments of the osteotomy was able to mantain the condyle in the presurgical position.
