Should I do a nose job or chin implant? (photos)

You are an optimal candidate for the so called profileplasty, which
consists in doing rhinoplasty and chin surgery at a time, a safe and
routinary procedure in experienced hands.Your nose needs basic
complete rhinoplasty via open approach to shave down the hump, reduce
the tip and narrow frontally, make plasties at your bulbous cleft tip,
eventually tip grafting and perform osteotomies; additionally I notice you have a very wide nasolabial angle which produces a very high and overly rotated tip, nostrils exposure and a piggy-nose deformity due to a very short nasal septul, this makes you a candidate for septal lenghtening and eventually some columellar or tip grafting. We are talking of a top difficulty rhinoplasty, you must research very well to find a surgeon with the right skills and talent to face such case.Your chin needs
anterior advancement and for this I recommend sliding genioplasty.Being an option, chin implants have serious disadvantages, specially in
the mid and long term, patients are rarely happy with them after 5-6
years, all are out by then or later.Consider the chin advancement by means of sliding genioplasty, the advantages are:-lifetime procedure, no more revision or renewal procedures-more natural than implants-no visibility of implant edges during gestures-improves
the double chin effect at the sub-mental muscles (floor of mouth)
hammock caused by lack of tension there; also improves the shape and
tension of perioral muscles; implants do no offer this feature-horse-shoe enhancement, covering the chin and also the jaw sides of it-no future displacements or neuritis of mental nerves-practically zero infections and 100% healing of bones-no
need for complex plates and screws that may need future removal; just
steel wires synthesis may suffice, they stay buried into bone callusThe cons are:-expensive, but cheap if you consider the lifetime pros-technically
demanding, few surgeons are experienced or comfortable (though I
personally perform 100% of the chin augmentations by this osseous
method, always after offering the patients both options)-scary for the patient (though not so much if you explain well the stuff around it)You'll
find in this website dozens of negative experiences with chin implants
in the short and mid term, do read my profile's Q&A and you'll find
them too. I am doing sliding genioplaties for 15 years with the highest
success and no one patient regreted, totall the opposite, I did many
chin implant removals and one staged sliding genioplasties to replace
them.

 Thank you for your pictures. I am in agreement that you could benefit from chin and nasal enhancement. I would recommend in my opinion performing both of those procedures in one operation. Please seek board-certified plastic surgeon or board-certified facial plastic surgery for consultation and recommendations. 

Based on your photos I would consider both. You should consult a board certified plastic surgeon for detailed evaluation and discuss your options. Good luck.
