I had a deviated septum repaired 27 years ago without issue. I saw another ENT about 15 years ago, and he removed polyps from both nostrils, again without issue. I then had a sleep study done with the blessings of the ENT, and I have been using a Bi-Pap. I sleep, I breathe, and use saline to clear passages. There are quality ENT's in practice, and you may wish to locate one and set your biases to the side until you hear a definitive plan. I am 73 and am pleased to have been well treated.
