"Neck dissection, also known as cervical lymphadenectomy, is the surgical procedure for the management of metastatic cervical lymphadenopathy. There are multiple types of neck dissection that vary by the structures removed 1. This article reflects the 2001 classification by the American Head and Neck Society and the American Academy of Otolaryngology-Head and Neck Surgery 1,2."
"Modified radical neck dissection involves removal of cervical nodes, levels I through V, as in classical radical neck dissection, but with preservation of one or more of the key extranodal structures (spinal accessory nerve, sternocleidomastoid muscle, and internal jugular vein). Although previously grouped by types (I through III), variation in practice makes it advisable to name explicitly the structures spared in a modified radical neck dissection (e.g. modified radical neck dissection with preservation of the spinal accessory nerve)."
