The submental triangle (or suprahyoid triangle) is a division of the anterior triangle of the neck.



It is limited:

  • behind by the anterior belly of the Digastricus,
  • in front by the middle line of the neck between the mandible and the hyoid bone;
  • below, by the body of the hyoid bone;
  • its floor is formed by the Mylohyoideus.


It contains:

  • one or two lymph glands, the submental lymph nodes
  • some small veins; the latter unite to form the anterior jugular vein
