Coarse facial features

Coarse facial features (coarse facies) is a constellation of facial features that are present in many inborn errors of metabolism.

Features include:
 * large, bulging head
 * prominent scalp veins
 * "saddle-like, flat bridged nose with broad, fleshy tip"
 * large lips and tongue
 * small, widely spaced and/or malformed teeth
 * hypertrophic alveolar ridges and/or gums

The head tends to be longer than normal from front to back, with a bulging forehead. This is because of the premature fusion of skull bones in the affected person.

Causes
Several conditions are associated with coarse facial features.
