  1. OVERVIEWCervical Lymph Nodes

  2. CERVICAL LYMPH NODES Arranged into deep & superficial chains. Deep jugular chain extends from base of skull to clavicle. Divided into superior, middle & inferior groups of lymph nodes. Superficial nodes drain to deep nodes. These are submental Submandibular Facial/buccal Preauricular Postauricular Occipital Superficial cervical Ant cervical

  3. Occipital nodes Retropharyngeal nodes Outer circle Nasopharyngeal tonsil Tubal tonsil Innermost circle Palatine tonsil Mastoid nodes IJV Deep cervical nodes Parotid nodes Paratracheal nodes Lingual tonsil Pretracheal nodes Inner circle Submandibular node Submental nodes CERVICAL LYMPH NODES

  4. SUPERFICIAL CERVICAL NODES Submental nodes- chin, middle of lower lip, tip of tongue & anterior mouth. Drain into submandibular nodes. Submandibular nodes- upper lip, lateral lower lip, lower nasal cavity, anterior mouth & skin of cheek. Drain into superior deep jugular nodes. Superficial cervical nodes (along EJV) receive drainage from cutaneous lymphatics of face, esp from around parotid gland, behind the ear, parotid & occipital nodes. Drain into superior deep jugular nodes. Nodes in posterior triangle lie along spinal accessory nerve. Drain parietal & occipital regions of scalp. Upper nodes drain to superior deep jugular nodes & lower nodes drain into supraclavicular nodes. Anterior scalene (Virchow's) nodes receive drainage from thoracic duct- located at junction of thoracic duct & left subclavian vein. Usually site of metastases from lower part of body (e.g. stomach). Supraclavicular nodes receive drainage from spinal accessory nodes & from infraclavicular sources.

  5. SUPERFICIAL CERVICAL NODES Occipital nodes Preauricular nodes Postauricular nodes Superf cervical nodes Submental nodes Submandibular nodes

  6. Preauricular nodes Parotid group Occipital nodes Facial (buccal) group Post. auricular nodes Submandibular nodes Superf cervical group Submental nodes Ant. cervical group SUPERFICIAL CERVICAL NODES

  7. Preauricular nodes Preauricular nodes Submandibular nodes Submental nodes Submental nodes Submandibular nodes LYMPHATICS FROM FACE

  8. DEEP CERVICAL NODES Superior deep jugular nodes Primary drainage- soft palate, tonsils, palatoglossal & palatopharyngeal arches, posterior tongue, base of tongue, pyriform sinus & larynx above vocal folds. Also from superficial nodes in upper head & neck (retropharyngeal, spinal accessory, parotid, superficial cervical & submandibular nodes). Middle deep jugular nodes Primary drainage- larynx above vocal folds, lower pyriform sinus & posterior cricoid. Receive secondary drainage from deep jugular nodes above them & lower retropharyngeal nodes. Inferior deep jugular nodes Primary drainage- thyroid, trachea & cervical esophagus. Receive secondary drainage from deep jugular nodes above them & paratracheal nodes.

  9. Post auricular nodes Preauricular nodes Occipital nodes Tonsil Ant & Post tongue Submental nodes JD nodes Submandibular nodes Common facial vein Superf cervical nodes Ant cervical nodes JO nodes Supraclavicular nodes Jugular lymph trunk Subclavian lymph trunk CERVICAL LYMPH NODES

  10. DEEP CERVICAL NODES Retropharyngeal & paratracheal nodes Lie posteriorly around midline viscera Receive from these viscera & from deep structures in midline of head- nasopharynx, posterior nasal cavity, PNS, posterior oropharynx. Drain towards deep jugular chain

  11. Facial vein DIGASTRIC (PB) JD NODES IJV JO NODES Intermediate tendon SUPRACLAVICULAR NODES DEEP CERVICAL NODES Masseter DIGASTRIC (AB) OH (Sup belly) OH (Inf belly)
