![]() ![]() These levels are Ia, Ib, II, III, IV, V, VI, VII, VIII, IX, X. Neck (there is a chain of lymph nodes on either side of the front of the neck, both sides of the neck, and down each side of the back of the neck) Under the jaw and chin. The lymph nodes of the neck are further classified by level. Suspect bacterial lymphadenitis if there is a short history of. Anterior Cervical (Superficial jugular) Superficial Cervical (External jugular) Return to Lymph Chains & Their Drainage Areas. These include the nasopharynx, pharyngeal wall, base of the tongue, soft palate, and larynx. Joint pain or swelling Rash Pallor (looking. Conversely, most structures drain ipsilaterally, except in the case of structures situated at the anatomic midlines. Lymph nodes make up part of the lymphatic system, which helps the immune system. On the right side, they flow directly into the lymphatic duct. The adenoids are lymph nodes located in the back of the throat behind the nose. On the left side, they drain either directly into the vasculature via the jugulo-subclavian venous confluence or directly into the thoracic duct. From there it moves into the spinal accessory chain adjacent to the spinal accessory nerve, or cranial nerve XI, and then meets the supraclavicular chain. This lymphatic drainage originates at the base of the skull, then proceeds to the jugular chain adjacent to the internal jugular vein. These lymphatic chains are strongly lateralized and typically do not directly communicate between left and right in the absence of a pathologic process. Aponeuroses bind them together with the muscles, nerves, and vessels of the head and neck. The head and neck contains a rich and elaborate lymphatic network of more than 300 nodes and their intermediate channels. ![]() A detailed understanding of the principle lymphatic nodal levels of the neck is required, including their anatomical configuration and boundaries, patterns of drainage, and risk of metastatic involvement in the context of malignancy. This knowledge is especially crucial in guiding the approach to proper locoregional therapy, whether by surgery or irradiation. As such, intimate knowledge of the anatomic relationships of the lymphatic nodal levels and the structures they drain is critical in the delivery of appropriate therapy in many patients with cancers of the head and neck. I had a sinus infection which went all the way down to my gum and infected it, and that was causing the problem. Several months ago the one on the left side swelled more and got very tender. The involvement of specific nodal groups is an indicator of pathologically-affected organs and tissues, especially in the context of malignancy. The superficial and deep occipital lymph nodes receive lymphatic drainage from the posterior aspect of the scalp, skin of the upper neck and a portion of the. Both sides of the back of my head have raised bumps which yes, are lymph nodes. Lymphadenopathy is a significant clinical finding associated with acute infection, granulomatous disease, autoimmune disease, and malignancy. It is inclusive of osseous, nervous, arterial, venous, muscular, and lymphatic structures. The head and neck, as a general anatomic region, is characterized by a large number of critical structures situated in a relatively small geographic area.
