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

Boundaries

It is limited:

• behind by the anterior belly of the Digastricus,
• in front by the midline 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.

Contents

It contains:

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