The most clinically useful system of classification of neck lymph nodes is grouping into levels I–V. Anatomical, clinical and pathological studies demonstrate that although generally lymphatic flow is from above downwards, level I is often bypassed and level V is seldom involved. Neck dissection is classified into radical, modified radical, selective and extended radical neck dissections. Recent studies demonstrate that elective neck dissection is beneficial to the outcome of oral cancer patients, but not necessarily to laryngeal and pharyngeal cancer patients. Modified radical neck dissection is as effective as radical neck dissection when performed in the elective situation. Selective neck dissection in the form of supra‐omohyoid neck dissection is useful as a staging procedure. Modified radical neck dissection is acceptable for the N1 neck provided postoperative radiotherapy is given.
