Facial asymmetry is a functional and esthetic pathology that can be related to condylar hyperplasia; the aim of this research was to asses the condylar size in the facial asymmetry. Twelve subjects was studies with cone beam computed tomography; the analysis was realized in the software Pax Zenith, Vatech (Korea 2011), using 90 kV and 120 mA and was realized anterior-posterior measurement, superior and inferior measurement and medial-lateral measurement of condylar head and was realized the relations with condylar position with the medial facial line and the position of facial point between superior central incisior, inferior central incisior and chin. The results show that the chin was displaced 6.5 mm from middle line being a hyperplasic condyle with a 2.7 mm more than no hyperplasic condyle. 1 mm of displacement of low central incisor was associated to 2.2 mm of chin displacement. The hyperplasic condyle presented more size and was posicionated 2 mm more lateral than non-hyperplasic condyle. Is conclude that the hyperplasic condyle present a clear influence in the facial transversal asymmetry and in possible to establish a relation between the size of hyperplasic condyle and the facial asymmetry.
