The jugulodigastric lymph nodes are found in the proximity of where the posterior belly of the digastric muscle crosses the internal jugular vein. Nodes are typically around 15 mm in length in adults, and decrease in size during old age. [1] They tend to be some of the largest lymph nodes in the cervical chain due to their significant lymphatic ...
The classification of the cervical lymph nodes is generally attributed to Henri Rouvière in his 1932 publication "Anatomie des Lymphatiques de l'Homme" [6] [7] Rouviere described the cervical lymph nodes as a collar which surrounded the upper aerodigestive tract, consisting of submental, facial, submandibular, parotid, mastoid, occipital and retropharyngeal nodes, together with two chains ...
Superior deep cervical lymph nodes situated in a triangular region bounded by the posterior belly of the digastric muscle, the facial vein, and the internal jugular vein form a subgroup - the jugulodigastric group. The group consists of a single large lymph node and multiple smaller lymph nodes. It is particularly involved in the drainage of ...
Supraclavicular lymph nodes. Supraclavicular lymph nodes are lymph nodes found above the clavicle, that can be felt in the supraclavicular fossa. The supraclavicular lymph nodes on the left side are called Virchow's nodes. [1] It leads to an appreciable mass that can be recognized clinically, called Troisier sign. [2]
The deep cervical lymph nodes are subdivided into a superior group and an inferior group. [3][4] Alternatively, they can be divided into deep anterior cervical lymph nodes and deep lateral cervical lymph nodes. [citation needed] They can also be divided into three groups: "superior deep jugular", "middle deep jugular", and "inferior deep ...
Physical signs of a peritonsillar abscess include redness and swelling in the tonsillar area of the affected side and swelling of the jugulodigastric lymph nodes. The uvula may be displaced towards the unaffected side. [3] Unlike tonsillitis, which is more common in children, PTA has a more even age spread, from children to adults.
Structure. The pretracheal lymph nodes lie anterior to the trachea. [1] They follow the anterior jugular veins either side of the midline. [1] They drain into the deep cervical lymph nodes on the right and the thoracic duct on the left. [1]
Farabeuf's triangle is the triangular space in the upper portion of the neck where the bifurcation of the carotid artery can be seen. It is limited: the rear: the jugular vein; internal below and beyond: the facial vein; above and beyond: the hypoglossal nerve. [1] This triangle serves as a reference to locate surgery elements that are in the ...
