Is a rhinoplasty my best option for a more defined nose? (Photos)

Thank you for your question and providing photos!
To me, it looks like you likely have something called a "bifid tip" which is essentially where the lower lateral cartilages of the nose (what gives the nasal tip its shape) diverge slightly at the midline and cause a central line or indentation. There are certainly degrees of this as well and I would say yours is on the fairly minor side of that.
As far as options to address this, I think it depends on how bothersome this is to you, but you could have a fairly conservative rhinoplasty just addressing the nasal tip without making other significant changes. This often involves suturing these cartilages closer together (less of a gap) and potentially adding a graft of some sort between them so the skin does not indent as much.
While filler is also an option, this is a somewhat controversial topic among rhinoplasty surgeons and you need to find someone who does this alot and most importantly, that they do it SAFELY. Personally, I don't love that option as much, but something you could possibly consider.
Hope this helps and best of luck!Kyle Kimura, MD

Hello and thank you for your question. Based on your photographs, you are a great candidate for rhinoplasty. Maneuvers for your surgery would include dorsal hump reduction, tip refinement, nasal tip deprojection, tip elevation, among other maneuvers. With good surgical technique, you could have an outstanding result. I recommend that you seek consultation with a qualified board-certified rhinoplasty surgeon who can evaluate you in person.

Best wishes and good luck.
