Coarse facial features (coarse facies) is a constellation of facial features that are present in many inborn errors of metabolism.^[1]

Features include:^[1]

• 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.

Several conditions are associated with coarse facial features.^[2]
