The lymph nodes of the neck

Although the lymph drainage of particular viscera is dealt with under appropriate headings (tongue, larynx, etc.), it is convenient to summarize

Anterior cervical here the arrangements of the lymph nodes of the head and neck as a whole (Fig. 219). These can be grouped into horizontal and vertically disposed aggregates.

The horizontal nodes form a number of groups which encircle the junction of the head with the neck and which are named, according to their position, the submental, submandibular, superficial parotid (or preauricular), mastoid and suboccipital nodes. These nodes drain the superficial tissues of the head and efferents then pass to the deep cervical nodes (although some lymph vessels pass direct to the cervical nodes, bypassing the horizontal nodes).

The vertical nodes drain the deep structures of the head and neck. The most important is the deep cervical group, which extends along the internal jugular vein from the base of the skull to the root of the neck (Fig. 198). The lymph then passes via the jugular trunk to the thoracic duct or the right lymphatic duct.

The superficial cervical nodes lie along the external jugular vein, serve the parotid and lower part of the ear and drain into the deep cervical group.

Along the front of the neck lies another group of vertically disposed nodes, the infrahyoid (on the thyrohyoid membrane), the prelaryngeal and the pre- and paratracheal nodes. These drain the thyroid, larynx, trachea and part of the pharynx and empty into the deep cervical group.

The retropharyngeal nodes, lying vertically behind the pharynx, drain the back of the nose, pharynx and Eustachian tube; their efferents pass to the upper deep cervical nodes.

Thus all structures in the head and neck drain through the deep cervical nodes either directly or ultimately.
