[Terminology and classification of condylar hyperplasia: Two case reports and review].

Condylar hyperplasia is characterized by the growth of mandibular condyle. Its etiology and pathogenesis remain controversial. It often occurs unilaterally and leads to facial asymmetry and malocclusion. In the literature, it was also classified according to anomalies accompanied by the growth of other components of the mandible. Differential diagnosis of condylar hyperplasia usually includes tumors of temporomandibular joint. In this article, we discuss the term "condylar hyperplasia" and its classification considering two patients with condylar growth.
