I had a septoplasty and sinus surgery a few years ago. I went to my ENT complaining about not being able to breathe through my nose - not at all, and I had very frequent sinus headaches and sinus infections. At first, he just wanted to give me a nasal spray and send my on my way because my nose looked fine from the outside. Eventually, he decided to send me for a CT scan and he was really surprised at how crooked my septum was when he looked at the scan results. He immediately told me that I needed to have surgery. I understand that most of these surgeries are outpatient, but I ended up having to spend one night in the hospital. You probably want to check into this beforehand so you can make plans for your kids. Do you have anybody that could keep your kids for a couple days following your surgery? That really would be helpful. I know that I would not have been able to care for my daughter in the days immediately following my surgery.
I do have to say that my recovery was harder than what I thought it would be, but it was worth it and I would do it all over again just to be able to breathe through my nose and sleep better. Before, I had to breathe through my mouth. I had to sleep with my mouth open and I woke up every morning with a sore throat. My husband also used to complain about me snoring all the time and that has pretty much stopped, unless I have a cold. I also wasn't sleeping well and I never felt rested no matter how long I slept.
I still get sinus headaches from time to time and I still get sinus infections, but not nearly as often. FYI - I haven't had any problems with scar tissue. Also, my husband accidentally hit me in the nose about 6-7 weeks after my surgery and it hurt so bad that I cried a little. It hurt horribly, but it didn't do any damage.
Also, you will probably want the prescription pain killers for the first couple of days but then you should be fine on Motrin.
