Unilateral Condylar Hyperplasia

- This is when one side of the lower jaw has grown more than the other
- UCH is thought be caused by an early bump to the jaw during early childhood
- This trauma causes more cartilage to be formed during on the side that got more injured
- This increased amount of cartilage then forms more bone on that side than the other
- Unfortunately, this usually gets worse with growth
- This assymmetric growth will sometimes continue for a number of years after the end of general body growth
- If the assymmetry is a functional or aesthetic problem then upper and lower jaw surgery may be recommended later
