[Neck dissection for Head and Neck cancers: state of the art and classification]. / Dissezioni linfonodali del collo per tumori del distretto cervico-facciale: note introduttive e classificazione.

ABSTRACT

The purposes of this article are to review the history and evolution of neck dissections, including an update on node levels and their anatomical landmark. A number of classification systems were proposed and subsequently established for neck dissection procedures. The system most often employed was published in 1991 by the American Head and Neck Society and American Academy of Otolaryngology- Head and Neck Surgery and revised in 2002 and 2008. According to this classification, neck dissections are grouped into four broad categories radical neck dissection (RND), modified radical neck dissection (MRND), selective neck dissection (SND) and extended neck dissection (ERND). The choice between different surgeries depends on type and site of head and neck tumor as well nodal involvement.
