I also have trouble breathing that makes me a mouth breather.
The best way to determine what specific changes will look good on your face, and what changes are surgically possible, is to do your research to find the top rhinoplasty specialists and consult with several of them in person. During your consultation, your photos can be computer-morphed to show how the changes to your nose will affect your appearance. DCF (Diced cartilage fascia) provides permanent results without the risk of warping or resorption of en bloc rib cartilage, and with a much lower rate of migration, infection, or extrusion than synthetic grafts. With a rhinoplasty surgeon experienced in this technique, diced cartilage wrapped in fascia is a consistent, reliable, long-lasting technique for creating dorsal augmentation with excellent results. Results are very surgeon dependent, so choosing the right surgeon is important. Good luck! @asianrhinoplasty @drdonyoo
It is difficult to tell from those photos. Typically, an Asian nose needs to be built up along the bridge because it can be somewhat flat. Your photos also show your nasal tip to be wide, so rhinoplasty can make the tip thinner and bring in the nostrils some as well. Be sure to see a rhinoplasty expert for consultation.
