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.
