“…If the upper lateral cartilage is too narrow, a spreader graft or a flaring suture can be considered [2,3]; if the scroll area is weakened, the alar batten graft would be a good treatment [1,4,5]. If there is a problem with the anatomy or supporting structure of the lower lateral cartilage, it is possible to consider lateral crural reshaping, such as the lower lateral crural turnover flap, alar contour graft, cephalic trimming of the lateral crura, and additional alar batten graft or lateral crural strut graft [6][7][8][9]. If there is a contracted scar on the nasal valve, it is difficult to correct nasal valve collapse, and scars can be corrected with Z-plasty [1].…”
