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.
Swelling of the deep lobe of the parotid gland may be seen intra-orally, and may also displace the tonsil. The minor salivary glands should be examined. The labial, buccal and posterior palatal mucosa should be dried with an air blower or tissue and pressed to assess the flow of saliva.
Parotid lymph nodes are lymph nodes found near the parotid gland in the immune system. More specifically, it can refer to: deep parotid lymph nodes;

About 33% of cases exhibit (with or without cervical lymph node swelling) tumors of skin, mediastinum, tonsils, gastrointestinal tract, and/or soft tissues. Some 10–20% of all cases are associated with precedent or contemporary Castleman disease , a benign lymphoproliferative disorder. [ 83 ]
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 .
Breast and trunk lymphedema can also occur but go unrecognised as there is swelling in the area after surgery, and its symptoms (peau d'orange and an inverted nipple) can be confused with post surgery fat necrosis. [16] Between 38 and 89% of breast cancer patients have lymphedema due to axillary lymph node dissection or radiation.
