Prognathism is a medical condition used to describe a protruding jaw. It may involve extension of bottom jaw, protrusion of upper jaw and the sticking of the upper and lower jaws than the rest of the face.

 

Causes

The causes of prognathism are congenital in some people where the upper or lower jaw protrudes with no underlying conditions. In others, prognathism is linked to some underlying conditions which include acromegaly, acrodysostosis and basal cell nevus synfrome.

Acromegaly is one of the causes of prognathism. It is a condition when the body secretes growth hormone excessively leading to the enlargement of the tissues.

On its own, acrodysostosis is an uncommon condition characterized with some defects such as small nose, shortened arms and legs, protruding jaw and mental retardation as well as hearing disorder.

Basal Cell Nevus Syndrome is also an uncommon congenital condition with heavy brow, distanced eyes and a wide nose.
