Had this done in 2014. My deviated septum was bad enough that they took scans of my head and the tech asked if I had ever been in a car accident (I haven't). I believe my ENT also did the balloon treatment in my sinuses in the same procedure. I was under general anesthesia the entire time.
My post-op experience wasn't great and here's the story…
TLDR: enormous nose bleed, hospital visit, packed nose, puked blood.
Some time after the surgery, after they had removed the gauze, I came home from work and immediately started having a nose bleed. Didn't think much of it but it didn't stop and there was a lot of blood. After about an hour of blood just streaming out of my nose we decided to do something. Urgent care wasn't busy and I got sent back right away. The doc pretty much just observed me. I don't remember him doing much at first. He finally said since the bleeding hadn't stop he was going to have to pack my nose. That meant nothing to me because I've never done that. Or when they did it during the surgery I was under anesthesia. Then about 3 male nurses (big dudes, looked like football players) walked in the room. I asked what they were there for and the doc said, "they are here to hold you down", which immediately got my attention.
If you haven't had your nose packed it's probably one of the worst and most painful experiences I've had. And I have a pretty high pain threshold. It's like a tampon. They shoved a cardboard/plastic cylinder up my nose as far as they could to insert cotton gauze. A nose that was already tender from surgery. Those dudes definitely held me down because my back was arching trying to come up off the bed. My wife at the time was in the room and I remember seeing her covering her mouth in horror. That stopped the blood from coming out my nose. Only now it was going down my throat. After looking in my throat repeatedly the doctor finally said they need to transport me to the ER and I might need surgery. So I rode in an ambulance to the ER of a major hospital. ER was busy and they had me on a gurney staged by the nurses station. I started feeling sick. Really sick. I tell someone I'm about to throw up and they give me a bucket and start wheeling me into a trauma room. I proceed to vomit all the blood I had swallowed for the last few hours. It was black and disgusting.
I guess they called my ENT because by 9 or 10 pm he showed up. He said everything looked okay and that I would need to leave the cotton gauze in for a few days. Evidently something hadn't healed completely and whatever blood that had clotted during the surgery came loose. Had a follow up and no issues after.
I wouldn't say it's helped with my snoring but I can breathe a little better. I am very averse to having things put up my nose now. Avoid covid tests like the plague.
