I had the surgery about 6 weeks ago. It worked 100% in my case. I was only getting 52% oxygen level and now am around 95%. Still have other medical problems, but sleep apnea is gone. I just had a second sleep study to confirm this. I would recomend the surgery, but it is painful and uncomfortable. Be sure to take the brand name liquid pain medicine your doctor prescribes, as it will make it comfortable. Good Luck.
