The parotid lymph nodes, form two groups in relation with the parotid salivary gland, viz., a group imbedded in the substance of the gland, and a group of subparotid glands lying on the lateral wall of the pharynx.

Occasionally small glands are found in the subcutaneous tissue over the parotid gland.

Their afferent vessels drain the root of the nose, the eyelids, the frontotemporal region, the external acoustic meatus and the tympanic cavity, possibly also the posterior parts of the palate and the floor of the nasal cavity.

The efferents of these glands pass to the superior deep cervical glands.

The afferents of the subparotid glands drain the nasal part of the pharynx and the posterior parts of the nasal cavities.

Their efferents pass to the superior deep cervical glands.

There is often argument over the existence of these parotid lymph nodes in the medical profession (particularly students) as their anatomy is often overlooked. These are not to be mistaken for the parotid gland also.
