What Can I Expect For My Profile From Chin Surgery Vs Rhinoplasty? (photo)

I would need to see you in person, from different angles, and in movement to answer this question accurately.  However, based on this one picture, I think you might benefit from angle of jaw implants as well as a chin implant. 

Angle of jaw implants are inserted at the back corner of your jaw where it turns from the up/down part to the forward/backward part (the area around where your molars are).  These implants come in two styles.  One style is designed to give you a wider appearance from the front, and the other is designed to make the line of the jaw lower and more back.  You would be considering the second type.  The result of this would be to make your jaw line more horizontal by lowering the back part of it.  This type of implant is not common so you may have some trouble finding a surgeon who does them.

The chin implant is supposed to be placed on the front side of the jaw bone, causing your jaw to have more projection forward, not downward.  This would also benefit you, but I don't think you need an overly large implant. 

As far as the nose profile is concerned.  It is a matter of personal preference, but you might want a little taken off of the top (dorsum/bridge).    You have a very straight dorsum and perhaps even a slight hump, which is fine, but a slight amount of removal would make it a bit softer and more feminine.

  Let me start out by saying that the proper way to evaluate the face, on profile, is for the jaw to be at a 90 degree angle with the neck.  In this picture your chin and face are pointing downwards, making the chin appear weaker than it may in fact be.  Aesthetically speaking, if the chin is weak, determined by an imaginary line drawn downward from the lower lip, a Chin Implant placed through an incision under the chin would augment the chin without affecting the bite.  

  The nose has a slight hump that could be removed but I can't evaluate the tip rotation or projection since the nose is also facing downwards and is not at the aesthetic rest/start point.  Be sure that the Rhinoplasty Surgeon, you select, understands and follows the proper aesthetics of facial (and nasal) beauty foir the creation of a naturally, more attractive face and nose.
