Alar batten grafts are what you need for the pinched tip. See a very experienced revision rhinoplasty surgeon for this whose work looks natural. Do not rely on imaging but on the skills of the actual surgical work.
Alar batten graft is usually shorter and goes on top of the existing lateral crus that keeps the nostril open while the lateral crural graft is longer and goes underneath the existing lateral crus thus is more effective than a batten graft. A batten graft is used more for the aesthetic benefits with some improvement in the valve function while lateral crural strut has both functional and aesthetic benefits. While both eliminate the convexity of the ala and improve the function of the external valve, the strut also may improve the function of the internal valve, depending on how it is place.
