SCOPE OF REGIONAL LYMPH NODE SURGERY

The regional lymph nodes are the cervical and upper mediastinal lymph nodes.

Terminology of neck dissection (Robbins et al. 19): A radical neck dissection includes the removal of all ipsilateral cervical lymph node groups, i.e., lymph nodes from levels I through V (submental, submandibular, cranial jugular, medial jugular, caudal jugular, dorsal cervical nodes along the accessory nerve, and supraclavicular), and removal of the spinal accessory nerve, internal jugular vein and sternocleidomastoid muscle. In a modified radical neck dissection the same lymph nodes are removed as in a radical neck dissection; however, one or more non lymphatic structures are preserved. A selective neck dissection is a neck dissection with preservation of one or more lymph nodes group routinely removed in radical neck dissection.
