Can a septum re-deviate after surgery?

It is not uncommon for septal deviations to recur.  It is more common with puberty, after trauma, or following surgery. Spurs don't usually "re-grow", if they are completely removed. New ones can form, however.I hope this helps clarify things for you. Good luck!

It can redecorate. It is impossible to fight all forces that want the septum to go back to where it was. A spur would not likely come back though.
