When my sleep doctor gave me the results of my sleep study, I was told that I had three options since my AHI was so low
AHI = 10.5/hr.) I was told I could do CPAP, or consider an ENT doctor exam, or wear an oral appliance. I did my research on all of them for effectiveness and if patients were compliant with their treatment. I finally decided to see an ENT doctor who told me that my nasal septum was deviated and told me that if I had surgery to correct that, that he would also do a turbinate reduction in my nose to make it easier for me to breathe since I have a limited amount of space in my nostrils for breathing. Many mornings when I wake up, my lips are very dry, which I think that, that could be an indication that I'm a mouth breather when I sleep. I read that it is much healthier to be a nose breather.
For surgery, make sure they give you anti-nausea medication (probably in the IV and a prescription), run a humidifier, protein for healing, lots of rest and liquids, sleep in a recliner, sinus rinse and mists, lip balm for your lips, have lots of tissues available for bleeding, and take fiber as anesthesia slows down the G.I. tract. People say this is a pretty easy surgery to recover from and that it does make a difference in a person being easier to breathe.
I'm getting a ResMed AirSense 10 AutoSet for Her machine as the machine I will start with. Thanks to the above posters, I have decided to use a full-face mask after surgery.
