I had a revision tip rhinoplasty for nostril asymmetry and my surgeon much removed my columella due to a misunderstanding. Now it looks flat and weird from the side and front as well, and my nosetrils look unnaturally close. My surgeon suggested PDA threads to even it out as opposed to fillers, but all I could find online was nose thread lifting and contouring. Would it work for a problem like this? Thank you for your advice!
