I had revision rhinoplasty with SMR of the septum and not septoplasty. What is the difference between septoplasty and submucous resection (SMR) of the septum? Is there such a thing SMR of the septum and SMR of the turbinate? Please explain to me the difference. My septum was not much deviated and was not the reason for my breathing difficulties. Is SMR more conservative than septoplasty? My breathing difficulties only got worse and my valve collapsed even more. Thanks!
