I had septoplasty and coblation of my inferior turbinates one week ago. My nose is whistling and constantly runny/crusty (Photo)

It's hard to tell from the photo if that's really a perforation.  Definitely have your surgeon check it out.  I agree that if it is a septal perforation that needs to be fixed at some point that you definitely need an expert. I have transitioned to doing all my septal perforation repairs endonasally (closed),  which is very tricky in some cases. Make sure you see a surgeon who specializes in perforation repair. Don't let a non-expert attempt to close the perforation. It makes it harder to revise it the attempt fails. You are wise to not want a button, by the way. 

Thank you for your question. I can understand your concern with having the perforation. However, whilst buttons can be used, they are not well tolerated and small perforations can be closed with very good results. As regards the surgery, an ENT surgeon would generally be more experienced in the repair than a plastic surgeon. In particular, seek out a rhinologist (an ENT surgeon that sub-specialises in conditions of the nose and sinuses). Best Wishes. Philip

Hard to tell by the pic . But you may have a perforation. If so it appears small and should be relatively easy to fix
