Selective neck dissection (SND) was reported as suitable after chemoradiation in patients with advanced regional disease. Reduced morbidity represents the major advantage of SND. In a situation in which there is a major fibrosis around the previously invaded nodes, resection of 1 or more nonlymphatic structures may be required. The current classification of SND could be implemented by the addition of extended selective neck dissection (ESND). The standard basic procedures for SND spare the sternocleidomastoid muscle (SCM), the internal jugular vein (IJV), and the spinal accessory nerve (SAN). When an SND is associated with the resection of 1 or more nonlymphatic structures, it should be termed ESND. All additional nonlymphatic structure(s) removed should be identified in parentheses. The proposal to subclassify SND not only in accord with the resected lymph node levels but also upon the nonlymphatic structures removed may be of some help to avoid potential misinterpretation. | lld:pubmed |
