Anatomy

The submental lymph nodes are situated in the submental fascial space. They are situated close to the midline. They are immediately superficial to the mylohyoid muscle.⁴

Afferents

They drain the lower lip, floor of the mouth, apex of the tongue, chin, and inferior/mandibular incisor teeth and their associated periodontium and gingiva.⁵

Efferents

They drain either to submandibular lymph nodes (which then drain to deep cervical lymph nodes), or to the deep cervical lymph nodes directly.⁶

Clinical significance

The most common cause of enlargement of the submental lymph nodes are infections (including viral infections such as mononucleosis, Epstein-Barr virus infection, and cytomegaloviral infections), toxoplasmosis, and dental infections (e.g. periodontitis)).⁷

The lymph nodes may be affected by metastatic spread from cancers of their drained territories.⁸
