The most common causes of enlargement of the submandibular lymph nodes are infections of the head, neck, ears, eyes, nasal sinuses, pharynx, and scalp. [1] The lymph glands may be affected by metastatic spread of cancers of the oral cavity, anterior portion of the nasal cavity, soft tissues of the mid-face, and submandibular salivary gland. [1]
The submandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space , and is paired on either side, located on the superficial surface of the mylohyoid muscle between the anterior and posterior bellies of the digastric muscle . [ 1 ]
Fascial spaces (also termed fascial tissue spaces [1] or tissue spaces [2]) are potential spaces that exist between the fasciae and underlying organs and other tissues. [3] In health, these spaces do not exist; they are only created by pathology, e.g. the spread of pus or cellulitis in an infection.

The paired submandibular glands (historically known as submaxillary glands) are major salivary glands located beneath the floor of the mouth.In adult humans, they each weigh about 15 grams and contribute some 60–67% of unstimulated saliva secretion; on stimulation their contribution decreases in proportion as parotid gland secretion rises to 50%.
