How can my nose tip support be reconstructed after a poor septoplasty? (Photos)

I had septoplasty for functional reasons, and the surgeon ended up resecting most of my septum, scooping out its inner part, leaving it with sort of a L-shape (as he described). This ended up in a loss of nose tip support, in what I think is columellar retraction, in my nose becoming pointier, and a decreased nasolabial angle. My goal is to recover my original nose shape. How realistic is it that this can be done? If it can be done, how can it be done?
