and Makek classified condylar hyperplasia into three categories, listed in the table below. Type 1 develops its characteristics from the horizontal vector, and Type 2 develops its characteristics from the vertical vector. Type 1 CH occurs much more common (15x) than Type 2 CH.

Condylar hyperplasia has an unknown cause. Several theories exist in literature which related to the cause of condylar hyperplasia. One theory states that an event of a trauma leading to increase in number of repair mechanism and hormones in that area may lead to increase in growth of mandible on
