THE LYMPH NODES OF THE HEAD AND FACE 



779 



The superficial parotid or preauricular lymph nodes (lymphoglandulae auriculares 

 anteriores) are situated between the parotid fascia and the parotid salivary gland. 

 The deep parotid lymph nodes, from fifteen to twenty in number, are embedded 

 in the substance of the parotid gland. The afferents of the superficial and deep 

 parotid nodes drain the eyelids, eyebrows, the root of the nose, upper portion 

 of the cheek, frontotemporal portion of the scalp, from the outer surface of the 

 pinna, from the external auditory meatus, and from the tympanum. Their 

 efferents pass to the upper deep cervical nodes. 



The subparotid nodes lie beneath the parotid gland, on the lateral wall of the 

 pharynx, and they are close to the internal carotid artery and the internal jugular 

 vein. Their afferents drain the posterior part of the nasal fossa, nasopharynx, 

 and Eustachian tube; their efferents pass to the upper deep cervical nodes. 



The facial nodes comprise three groups in the course of the afferents of the 

 submaxillary nodes. (1) A maxillary, over the infraorbital region; (2) a buccal, 

 upon the outer surface of the Buccinator where that muscle is pierced by the 

 parotid duct; (3) a mandibular group, upon the outer surface of the mandible, 

 at the anterior margin of the Masseter muscle, beneath the Platysma and in 

 contact with the facial vessels. Their afferent vessels drain the eyelids, the 

 conjunctiva, integument, and mucous membrane of the nose and cheek.

The internal maxillary nodes (lymphoglandulae faciales profundae) are deeply 

 placed beneath the ramus of the mandible on the outer surface of the External 

 pterygoid, in relation to the internal maxillary artery. Their afferent vessels 

 'drain the temporal and zygomatic fossae and the nasopharynx; their efferents 

 ipass to the upper nodes of the deep cervical group. 



The lingual nodes (lymphoglandulae lingual.es) are two or three small nodules 

 lying on the Hyoglossus and under the Geniohyoglossus. They form merely nodal 

 substations in the course of the lymphatic vessels of the tongue. 



The retropharyngeal nodes (Fig. 558) lie in the buccopharyngeal fascia, 

 behind the upper part of the pharynx and in front of the arch of the atlas, being 

 separated, however, from the latter by the Rectus capitis anticus major. Their 

 afferents drain an extensive area, comprising the nasal fossa?, the nasopharynx, 

 and the Eustachian tube as far as the tympanum; their efferents pass to the 

 jupper nodes of the deep cervical group.
