- Clinically/radiologically N+ neck: Modified radical neck dissection (Levels I-V)
- Clinically/radiologically N0 neck
- Elective treatment of the neck (Levels Ia,b, IIa and III )
- Elective neck dissection and elective radiotherapy are equally effective
- Known risk factors for occult neck disease are
- Tumour size >4cm
- High-grade histology
- Extraglandular tumour extension
- With a clinically or cytologically malignant tumour, electively clear all nodes in Level I to avoid having to redissect Level I
- If positive on frozen section, proceed to modified neck dissection
- If frozen section not available, then histology of lymph nodes guides subsequent treatment
