The submental triangle (or suprahyoid triangle) is a division of the anterior triangle of the neck.
It is limited to:
- Lateral (away from the midline), formed by the anterior belly of the digastricus
- Medial (towards the midline), formed by the midline of the neck between the mandible and the hyoid bone
- Inferior (below), formed by the body of the hyoid bone
- Floor is formed by the mylohyoideus
- Roof is formed by Investing layer of deep cervical fascia
(The contents of the triangle actually lie in the superficial fascia over the roof of submental triangle)
