One Side of Columella Sticks out More/ Left Nostril is Smaller Than Right One Due to Columella or Septum? (photo)

Protrusion of Septum? I had closed rhinoplasty 5 and a half months ago to shave down a bump and to remove a bit of cartilage from tip. I always had somewhat of a crooked bone/deviated septum but it did not show so I decided not to fix it. After surgery, nostrils looked different size since one side of the columella sticks out more in one nostril. What procedures can be done to fix this, and how minor/major is the procedure? I am curious/worried. I really do not want to have another surgery, unless it is very minor.
