The preauricular deep parotid lymph nodes (anterior auricular glands or preauricular glands), from one to three in number, lie immediately in front of the tragus. Their afferents drain multiple surfaces, most of which are lateral in origin.
The deep parotid lymph nodes are lymph nodes found below the parotid gland. 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 .

The classification of the cervical lymph nodes is generally attributed to Henri Rouvière in his 1932 publication "Anatomie des Lymphatiques de l'Homme" [6] [7] Rouviere described the cervical lymph nodes as a collar which surrounded the upper aerodigestive tract, consisting of submental, facial, submandibular, parotid, mastoid, occipital and retropharyngeal nodes, together with two chains ...
The superficial parotid lymph nodes are a group of lymph nodes anterior to the ear. 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 .
It is called preauricular sinus which, according to the U.S. National Institutes of Health, or NIH, "generally appears as a tiny skin-lined hole or pit, often just in front of the upper ear where ...
The mastoid lymph nodes (retroauricular lymph nodes or posterior auricular glands) are a small group of lymph nodes, usually two in number, located just beneath the ear, on the mastoid insertion of the sternocleidomastoideus muscle, beneath the posterior auricular muscle.
The superficial cervical lymph nodes are lymph nodes that lie near the surface of the neck.. Some sources state simply that they lie along the external jugular vein, [1] while other sources state that they are only adjacent to the external jugular vein in the posterior triangle, and they are adjacent to the anterior jugular vein in the anterior triangle.
