maxillary prognathism

Maxillary prognathism is a protrusion of the maxilla, and is also a common feature of many populations.

In disease states, maxillary prognathism is associated with Cornelia de Lange Syndrome; however, so-called false maxillary prognathism, or more accurately, retrognathism, where there is a lack of growth of the mandible, is by far a more common condition.
