Do rhinoplasties and deviated septums cause nasal fungus infections? (Photo)

An open rhinoplasty was performed on just my tip (no bone broken) back in 2005. One plastic surgeon told me my septum is deviated. The past few years I've noticed a foul-smelling (dirty socks) smell running from my nose. One plastic surgeon says this is normal with rhino patients. Is this normal? Could this be a fungus infection? Would this be a difficult revision surgery to straighten and reduce my collumella? Thanks you.
