I feel I have to add my voice to this issue. I was having sinus problems and “everyone” had an answer, including my GP. “You need washouts, you need to address your deviated septum, etc etc.” I also was lucky enough to be referred to a consultant who was extremely reluctant to intervene. I was initially a bit annoyed but, when I pushed for answers, he addressed the fact that surgery had limited potential benefit and a fair bit of risk. He even said that at times when patients say they feel better after surgical intervention, he was not entirely convinced. He said in my case he would intervene surgically only if the was so much blockage I couldn’t use the steroid sprays. And you know, even though I was being told he couldn’t do anything for me, except advise about non surgical approaches, I felt so much better and in control. And I really agree with @nrd1 that many of the “old” well intentioned surgical approaches were based on logic and engineering but with a complete lack of understanding of the complexity of the nose and sinuses. Hopefully they are learning.
