Rhinoplasty revision needed? The shape of my nose is still not as round but more triangular shape

Rhinoplasty revision needed? Hi all, so I got a rhinoplasty a year ago that required my ear cartilage. I had the tip done and rounded out my nostrils. However, the shape of my nose is still not as round but more triangular shape. The doctor said a revision can be done that is less invasive as the first. He said he would harvest cartilage from the roof of my mouth for this bc it is a stronger cartilage to hold shape of nostrils. Can't find this procedure anywhere is my concern.
