I am going for tertiary rhinoplasty and want to bring down the tip and lengthen my nose so that my nostrils are less visible from front. My surgeon said he will use ear cartilage for that. I have read that rib cartilage is stronger. Which cartilage is better in this case? what are the risks for both? He also said to go for filler rhinoplasty first so that I can see how results will look, and then go for the surgery. Is it safe to go for permanent rhinoplasty within a month of injecting filler?
