I can't speak for the throat reconstruction aspect but I had a septoplasty a couple years ago. That is basically where they go in and removed excess tissue and enlarge and unblock the nasal passages. The procedure didn't take too long and after the initial day the pain wasn't too bad, nothing that a couple hydrocodone a day couldn't knock down, which, I would imagine they will prescribe for pain control afterwards. The only super bad pain I had was in recovery after the procedure. As I started coming to I was suddenly hit with a ton of pain in my nose/face area. The best way I could describe it was as if my nose had been completely smashed with a brick. I called, well, yelled for the nurse. She came in, injected some meds into my IV and I was good within about 3-5 min. Took my hydro as prescribed after that and didn't have anymore pain for the two week recovery. The only really uncomfortable thing is that they pack the sinuses. This is only uncomfortable because it feels like your nose is stuffy, like when you have a bad cold. When they remove the packing, usually in about 2 weeks, it feel so awesome to be able to breathe clearly again. Your sense of smell might even be heightened for a while like mine were. Ultimately it didn't help quite as much as I had hoped for but there was some improvement. It sounds like you are getting the whole package deal though so your outcome may be much greater than mine. I wish they had, at the very least, removed my tonsils as they are larger than they should be. Fortunately my sleep apnea is under control with CPAP therapy. Using my machine I usually have 1-3 events an hour which is down from 180 events an hour at my initial sleep study. I still get sleepy during the day but my sleep doc prescribe provigil and it works great. I hope your procedure goes well and works great for you.
