The '''neck dissection''' is a [[Surgery|surgical procedure]] for control of neck [[lymph node]] [[metastasis]] from [[squamous cell carcinoma]] ('''SCC''') of the head and neck.<ref>{{cite web |title=Neck dissection: MedlinePlus Medical Encyclopedia |url=https://medlineplus.gov/ency/article/007573.htm |website=medlineplus.gov |access-date=17 February 2022 |language=en}}</ref> The aim of the procedure is to remove lymph nodes from one side of the neck into which cancer cells may have migrated.  Metastasis of squamous cell carcinoma into the lymph nodes of the neck reduce survival and is the most important factor in the spread of the disease. The metastases may originate from SCC of the upper aerodigestive tract, including the oral cavity, tongue, [[nasopharynx]], [[oropharynx]], [[hypopharynx]], and [[larynx]], as well as the [[thyroid]], [[parotid]] and posterior scalp.{{cn|date=February 2022}}
