1. Management of the neck in head and neck cancer involves addressing clinically negative (N0) and positive (N+) lymph nodes. 2. For N0 necks, elective neck dissection may decrease recurrence rates for high-risk primary sites. For N+ necks, selective neck dissection is adequate for early stage single node involvement without extracapsular spread. 3. Post-operative radiotherapy improves local control for N+ necks with adverse features like multiple nodes, extracapsular spread or positive margins. Concurrent chemoradiotherapy is preferred for advanced N2/N3 disease.
