I had a revision for a droopy, bulbous tip and my surgeon actually derotated my nose so that I have a witch nose when I smile. I had a droopy tip before; it's twisted down to the left. It's also quite painful, causing valve collapse, and affecting breathing and nostril position. I was derotated by injury to the left. How do I figure out how many degrees I need to be rotated again to have a straight nose that sits in my "aesthetic triangle"?
