Would a rhinoplasty and sliding genioplasty improve my profile? (Photos)

Hello,
Thank you for your question. Based on your limited view you may benefit from the dorsal hump removal and probably augmentation of the radix for a nice forehead nose pass. Since a nose is a 3 dimensional structure the nose should be harmonised from all sides. For your chin you may benefit either from the chin implant which is hard when you touch, or fat injection which is softer for touch. Both surgeries and possible breathing issues can be addressed in one surgery. 
Natural noses which suit each patients unique facial features are achievable thanks to the Closed Atraumatic rhinoplasty which protects the anatomy of the nose, strengthens the weak parts, reduces the swelling and prevents tissue damage. The healing process is accelerated as well. It is possible to achieve a scar free, defined and significantly reduced noses without opening the nose and compromising the functional issues with the Closed Atraumatic Technique.

You appear to be a good candidate fir rhinoplasty. Options fir the chin include either a chin implant or sliding genioplasty.  the chin implant is far simpler and more surgeons are comfortable with chin implants compared to the sliding genioplasty.
