MEZINÁRODNÍ CENTRUM KLINICKÉHO VÝZKUMU „TVOŘÍME BUDOUCNOST MEDICÍNY“ Neck ENT Clinic of Masaryk university, Brno Faculty St. Ann Hospital Head: Ass.prof. Gál Břetislav, MD, Ph.D. Pekařská 53, Brno , 656 91 Neck - anatomy Superior boundary – inferior edge of mandibula, mastoid process and protuberantia occipitalis ext. Inferior boundary – plain formed by the suprasternal notch, clavicle and the spinous process of the seventh cervical vertebra. Osteomuscular system is adapted to the upright human posture. Visceral part of the neck contains upper aerodigestive tract, the carotic sheath and its contents on each side and cervical lymphatic systém There is on the neck cca 200 lymph nodes Lymph nodes of the neck Nodi cervicales superficiales Along v. jug. ext. tributary zone: parotid gland, retroauricular region, intraparotic and occipital lymph nodes. Nodi lymphatici cervicales profundi They are in the carotid sheath. Superior group (subdigastric) Lymph channels lead to this regional lymph nodes (group) from the tributary tissue area: soft palate, tonsils, radix linguae, supraglottis, sinus piriformis. Nodus jugulodigastricus = Woodova uzlina= Küttnerova uzlina= Chassegnacova uzlina je v Middle group Tributary tissue area: supraglottis, glandula thyreoidea, sinus piriformis. Boundary to the crossing of m. omohyoideus and carotid sheath. Inferior group Tributary tissue area: subglottis, trachea, cervical oesophagus, glandula thyreoidea. „Great venous angle“ = the left jugulosubclavian angle. In this area is Troisier-Wirchow lymph node. Ductus thoracicus (thoracic duct) receive afferents from the lower half of the body, the cranial area. Lymphatic chain at n. accessorius Tributary tissue area: nasopharynx, oropharynx, paranasal sinuses.. Lymphatic chain along vasa transversa colli nodi supraclaviculares – closely above clavicula. Special groups of lymphnodes Nodi submentales, retropharyngei (the greatest Rouvier lymph node), paratracheales, nodus praelaryngicus (Poirier lymph node). Classification of cervical lymph nodes I submental and submandibular group II upper jugular group III middle jugular group IV lower jugular group V posterior triangle group VI anterior compartment group The Memorial Sloan Kettering Cancer Center classification Investigation • inspection • palpation • diagnostic imaging: • ultrasound, Doppler technique - provide information about vascular lesions, distinguish between cyst and solid tumor • computed tomography - allows greater differentiation : vascular lesion, tumors, cysts - including their position and extent • biopsy • cervical lymphography - is of little clinical value when compared with other methods of investigation. • MRI • Scintigraphy Summary of findings of palpation • form and size in cm, • site (localisation), topographic description • consistency - soft, elastic, fluctuant, firm or hard • mobility - vertically or horizontally, fixed or adherent • pulsation, skin - appearance of the skin, comparison to the surrounding tissues „Sentinel lymph node“ • First lymph node to which the lymph is coming from primary tumor. If there is no metastasis, the probability of metastatic spread is low. • Identification – • Before surgery – lymphoscintigraphy 1 day before surg. • During surgery - peritumoral application of lymphotropic agent (colloid solutions marked with radioactive technetium, stain). • Palpation- up to 1/3 of cases false negative or false positive. • UZ - sensitivity 94 % a specifity 91 % (depends on experience of interpreter) • FNAB fine needle aspiration cytology and biopsy guided by ultrasound - až 76 % sensitivity a 100 % specifity • Reliability of CT scan for metastasis into neck lymph nodes is given about 72 % - 93 % • PET reveals higher sensitivity, but lower specifity than CT scan. • Combination of evaluation methods shows presence of neck metastasis approx. in 70 % of cases. About 30 % of ill without clinical symptoms of metastasis is threaten with locoregional relapses from micrometastastatic disease from micro metastasis in regional lymph nodes. Utilization rate Cancer metastases into neck lymph node Cancer of thyroid gland Differential diagnosis of lumps of the neck Lymphnodes X Extra lymphnodes • Inflammatory Cervical Lymphadenopathy • Tumors • Congenital Anomalies Inflammatory Cervical Lymphadenopathy acute - lymph nodes are painful Chronic non specific lymphadenitis shows on repeated infections in the region of pharynx in past. Persistent or recurrent lymph node swellings are not compatible with a diagnosis of nonspecific lymphadenitis. Chronic specific lymphadenitis tuberculosis, sarcoidosis. Lymphadenitis reticullaris abscedens Cat Scretch Fever the pustulous primary focus, which tends to ulcerate, occurs in the skin, . This is followed 1 to 5 weeks later by a regional lymphadenopathy. In one third of cases a fistula forms. Is caused by the cat scratch virus. Tularemia Lymphadenitis with changes in blood account mononucleosis infectiosa, rubeola, adenovirosis, hepatitis epidemica, viral pneumonia, listeriosis, toxoplasmosis, lymphadenitis after hydantoin Rare lymphadenitis collagenases, syphilis, mycosis.

RT/CHT/CHRT The methods of surgical treatment of lymph node metastases Surgery from external approach – in case of primary surgical treatment, combined with Radiotherapy/radio chemotherapy Non surgical treatment – in case of „organ saving protocols“ - Radiotherapy/radio chemotherapy The methods of treatment Prescalene node biopsy (Daniels operation) The radical curative neck dissection (Resectio venae jugularis internae en bloc sec. Crile 1906) - the upper boundary of the operation is the base of the skull and the lower boundary lies at the level of the clavicle. The sternocledomastoid muscle, the internal jugular vein are removed. The goal of neck dissection is complete removal of lymph nodes and vessels between the superficial and deep cervical fascia. Functional deck dissection- the sternocleidomastoid muscle, the internal jugular vein, the accessory nerve are preserved. An elective neck dissection is a neck dissection carried out in the absence of palpable lymph nodes for a primary tumor which experience has shown to have a high metastatic rate - oropharynx, hypopharynx, supraglottic larynx, the base of the tongue. The purpose of this operation is to deal with micro metastases.
