Nose Job After Jaw Surgery, What Do You Suggest? (photo)

Surgical repositioning of the jaws is well recognized as affecting the aesthetics of the nose.  Upper jaw repositioning will affect primarily the nasal base and may also influence tip projection and rotation.  Lower jaw surgery will affect the nose-face proportions and facial profile.  From the photos you provided it is too difficult to make valid recommendations.  I suggest you seek out a few opinions from bona fide expert rhinoplasty surgeons.

The nasal structures rest on the upper jaw and palate. Surgery of the jaw can alter the shape of the nose and even cause buckling of the nasal septum. Septorhinoplasty can help improve your nose. For the photos posted, I suggest softening the hump, raising the tip of your nose and narrowing your nose.
You should seek out a specialist in rhinoplasty for a consultation.

It is important to wait several months after the jaw surgery before undergoing elective cosmetic surgery.  The options with the rhinoplasty are to reduce the bulbous tip, remove any hump across the bridge, and narrow and refine the pyramid of the nose to create a more refined and feminine appearance.  This is done under a general anesthesia and takes approximately an hour and a half.
