Do I have inverted v deformity or saddle nose deformity? (photos)

You’ve been told a lot of techno speak. If you can breathe ok and are pleased with the result there’s nothing to do. You do not have an open roof or inverted v. If you want some further refinement I suggest you find a surgeon who takes a more simplified approach.

Based on your photos, you are a candidate for revision rhinoplasty. While I don't discretely see an open roof deformity, the bridge is low and appears a bit washed out. The open roof can be felt during an examination, so that is very important. Be sure to see a rhinoplasty specialist for consultation.

Yes, it appears that you do have an inverted V deformity. This may occur when the middle vault (composed of the upper lateral cartilages) is weakened from surgery and scar contracture continues to push these cartilage elements down while the bone of the boney vault (the nasal bones) remains stationary. Disruption of the keystone means that the upper lateral cartilages were disrupted from their attachments to the nasal bones; this is another reason for a potential inverted V deformity if not correct properly. You need a very complex revisionary rhinoplasty. You should see an actual plastic surgeon (trained in plastic surgery residency and ideally aesthetic plastic fellowship) who specializes in rhinoplasty. Best of luck.
