How risky would revision be for pinched tip/parenthesis deformity? (Photos)

From your photographs it looks like you may have cephalically positioned lower lateral crura (meaning that they angle too far up toward the eyes). This can cause the parentheses deformity you mentioned. The result is that there isn't adequate underlying structural support of the nostril margins which then leads to the tip pinching.Lower lateral crural repositioning can a great way to fix this problem. This involves rotating the tip cartilage downward so they aren't angled so far up.This is an advanced rhinoplasty maneuver and not all rhinoplasty surgeons are well versed in performing it. With a surgeon comfortable with the technique it should be possible to improve the appearance of your tip though.You can read more about pinched tip rhinoplasty at my web reference link below.

I would definitely give your nose more time, as some or all of this may improve.  Find a plastic surgeon with ELITE credentials who performs hundreds
of rhinoplasties and rhinoplasty revisions each year. Then look at the
plastic surgeon's website before and after photo galleries to get a
sense of who can deliver the results. Kenneth Hughes, MD Los Angeles, CA
