Large level 5 nodes may contain metastases from nasopharyngeal and thyroid primary malignancies. It is known that occipital and mastoid, lateral neck, scalp, nasal pharyngeal regions drain to level 5 nodes. The lymph nodes contained within level 5 of the neck include the supraclavicular nodes. Its boundaries are the posterior border of sternocleidomastoid anteriorly, the anterior border of trapezius posteriorly and the superior border of the clavicle inferiorly. Where FNAC is unable to give a definitive diagnosis, core or excision biopsy is undertaken for formal histology to guide further management of the patient.Īnatomically, level 5 of the neck is also referred to as the posterior triangle. This can be performed with or without ultrasound guidance depending on whether the lump is easily palpable, or depending upon the risk of damage to surrounding structures. Ĭommonly, fine needle aspiration for cytology (FNAC) is performed in the outpatient setting as the initial ‘biopsy’. Clinical features of particular concern include: large size, a firm, rubbery or hard consistency, skin ulceration or fixation or if the node lies in a supraclavicular position. After conducting a thorough clinical examination, serological, radiological and histological investigations are carried out as necessary to confirm the diagnosis. The obvious concern in the majority of cases is malignancy and the otolaryngologist is obliged to investigate based upon the clinical presentation and risk factors in each individual case. Only a doctor or health care professional can determine the exact purpose of the enlargement of supraclavicular lymph nodes.Patients with persistent neck lumps are commonly referred to otolaryngologists from both primary and secondary care physicians. The left one is responsible for lymphatic drainage of the thorax and abdomen (via the thoracic duct). ![]() The right one is responsible for lymphatic drainage of the mediastinum (middle section of the chest cavity), lungs, and esophagus ( Overview of the Esophagus – ). There are two supraclavicular lymph nodes. The function of the supraclavicular lymph nodes is to filter fluid in the body. These lymph nodes are responsible for draining the lymphatic fluid from the neck and head regions.Īnother – Anterior Cervical Lymph Nodes Function Suboccipital (junction between the back of the head and neck).Posterior cervical (on the side of the neck near the back). ![]() Jugular (on the top of and underneath the sternocleidomastoid muscles). ![]()
