You had surgery for the septal correction .
BUt after 3 years you have this problem.
First of all the bone doesnot grow again .
And if the tilt you see has come up now then it should not be because of the surgery or the septum bone .
Do you have any other problem like nose blockage or sneezing
etc if yes then it could be because of the mucosa ie skin of nose which is edematous and you are feeling it to be abnormal.
Get an ent check up as you need examination .
