Jaspar, What is the size of the node, is it palpable? original TN stage? Studies show there is better outcome with a planned neck dissection than a "wait and see approach." Some do it anyway, regardless or when there are signs of an incomplete response, such as a palpable node, scan. On another note, most scans are clear at three months, and could be reactive. Personally, I would rather do a neck dissection, although the choice is yours, a lot can happen in three months. There are risks with any surgery, and the neck is a complicated area with major body functions involved, but the ENT's make it seem easy, plus their experience counts.

Good luck with your decision.
