Mine has been a year and a half. I asked my surgeon the same thing prior to surgery and he said in recent years they are cutting more of the septum and I was told, there is basically no chance of recurrence. Full disclosure, I am also an employee at Mayo, in Public Affairs, and if you are in Rochester and want to meet in person, please send me a message and we can try to connect. The procedure for me has changed my life. I feel amazing!! The first few days are really hard and rehab takes a commitment, but it was all worth it.
