Structures removed in radical neck dissection are all except
Ans. is 'd' i.e., Vagus nerve Radical neck dissectiono During radical neck dissection, following are removed.a) Lymph nodes of submental, submandibular, upper, middle and lower jugular, and lateral (posterior) trial regions, i.e. Level I to V along with its fibrofatty tissue.b) Stemomastoid muscle.c) Internal jugular vein.d) Spinal accessory nerve.e) Submandibular salivary gland.f) Tail of the parotid.g) Omohyoid muscle.o Following structures are saved -i) Carotid arteryii) Brachial plexus, phrenic nerve, vagus nerve, cervical sympathetic chain, marginal mandibular branch of fa>> lingual and hypoglosal nerve.Modified neck dissectiono It is similar to radical neck dissection but with preservation of one or more following structures -i) Spinal accessory nerveii) Internal j ugular veiniii) Sternocleidomastoid muscleo Thus, both radical neck dissection and modified radical neck dissection remove level I to V neck nodes.
