I think my inverted v is caused by open roof deformity due to osteotomies not being done during primary rhinoplasty. Can osteotomies be done to correct that? I’ve read that spreader grafts with septal cartilage is the best but that most patient don’t have enough left after their primary rhinoplasty. Is this true? I just had a slight hump removal and still have significant height left. How can I know if I have enough septal cartilage? I don’t want to harvest cartilage from somewhere else
