Bloop, this is why we have to be our own strong advocates. I'm assuming you won't need that ENT anymore because you're being promoted to dealing with the oncologists, head and neck surgeons and R.O.
I think we've all had to learn the hard way not to accept"it's nothing" it's not cancer" even though scans, symptoms and swollen lymph nodes are present.

Right now you just need to recover and heal from surgery and prepare yourself for the next step. Buff up nutritionally and get some extra calories on board. I found the Magic Bullet, a tiny but powerful blender to be my life saver in making smoothies and other foods. I blended everything in sight in that gadget and it comes with plastic containers with lids so you can store the potions. I think it cost $50 but well worth it.
( P.S. I don't work for the company)
Good luck in the weeks ahead,
Nancy
