Condylar Hypoplasia Type 1 is a condition where the lower jaw joints, called condyles, grow unevenly. In this condition, both condyles are growing, but at different rates, which leads to asymmetry and abnormal shape of the jaw joint. This can result in facial unevenness and problems with how the upper and lower teeth fit together. It can also cause limited jaw movement and difficulty in opening or closing the mouth properly. The onset of Condylar Hypoplasia Type 1 usually occurs during puberty. This condition leads to horizontal growth, resulting in mandibular prognathism (protruding lower jaw). The growth process typically concludes in the early to mid-20s.
