Please, need a 2nd opinion, rhinoplasty & septum 1 year ago & nose still not straight (Photos)

Hi, I had rhinoplasty and septum plastic over 1 year ago and my nose is still not straight and will also be so. I asked my surgeon why he wouldnt straighten my nose when I told him to do so, and then he said he was afraid that the nose could collapse. Is this really true or is he just unskilled? So my 2 big questions are: - Is it possible to still make my nose straight? - The side wall on the outside of my nose are much higher than the other side.Is it possible to make it equal to other side
