ABSTRACT
The lymphatic vessels and regional nodes of the nasopharynx in 70 foetuses and infant cadavers were studied with the method of injection of the lymphatics of the organ.There is a network of lymphatic capillaries in the mucous membrane of the nasopharynx, which drains into the submucous lymphatics. The latter join together to form a number of efferent ducts.The efferents emerging from the posterior wall of the nasopharynx end in the retropharyngeal lateral and medial nodes, or pass to the posterior aspect of the internal carotid artery and internal jugular vein and end in the upper deep cervical nodes lying deep to the tip of the mastoid.The lymphatics emerging from the lateral wall drain into the nodes right under the base of the skull anterior to the internal carotid artery and internal jugular vein, or descend to the jugulodigastric node, and the upper deep cervical nodes between the beginning point of the lingual artery and the bifurcate point of the common carotid artery.
