I love nurse practioners - they are so much more accessible than doctors but would I trust them over someone with 12 years of formal medical school training - not. But if you have been delegated to an NP then you probably have less to worry about. To answer your other question. Most of us are "followed" on 6-8 week intervals the first year, spacing out in successive years. My head & neck surgeon informs me that 2 months is enough time to deal with any issues, but consider that this time table is for post treatment patients.

With long term antibiotic therapy for a difficult to control infection, it may take 2 months to ascertain whether it's making a difference.

I do have to add a caution here for OTHERS reading this thread that we typically recommend that if you don't respond in 2 weeks to antibiotics then you need to see a specialist like an ENT or a head & neck surgeon (sorry if this is confusing to you Amanda).
