What should I do to achieve facial balance? Small chin & jaw, nose too big for mouth (Photo)

A chin implant would improve your shape in the front. You have a few options to improve the projection and symmetry of your chin and profile. If you’re not sure you’re ready for surgery, but still want to improve and strengthen your chin, I’d suggest augmenting your chin with Sculptra and/or Voluma. If you like your new look, you can make it permanent with a chin implant. I hope that helps.

Adequate chin projection is often determined by the the apex of the chin aligning with a vertical dropped from the lower lip   Your chin appears to meet that requirement already. You do seem to be a candidate for liposuction of the neck as there appears to be a small amount of fullness there. In addition the tip of your nose appears broad and droops when you smile. . those features could be improved upon if they bother you.

A chin implant can accomplish augmenting the chin forward for better facial balance and proportions.  Chin implants are manufactured and the large array of thicknesses, sizes, and shapes which is best determined at time of the consultation and examination.  The implant can be placed through a small incision underneath the chin under local anesthesia as an outpatient procedure.  For many examples, please see  the link and the video below

From your profile photograph it appears that you have a slightly weak chin and some excess fat under the chin. From your frontal view you could be a candidate for rhinoplasty surgery as well, however it depends on your concerns. The combination of rhinoplasty, chin augmentation and sub-mental liposuction could provide the sculpted look you are wanting. The best way to know that is to go to some consultations and have imaging performed to show you the proposed results and what these procedures could achieve for you. Then review the surgeons before and after photographs of patients with similar concerns to ensure expertise and natural looking results. See examples in the link and video below. Best regards, Michael V. Elam, M.D.

 Hi, I have performed many facial shaping procedures using dermal fillers, silastic facial implants (cheek, chin), liposuction and/or facelifts for over 30 years.  Following my beauty principles, men look chiseled and handsome with angularity in the cheeks, chin and mandibular angles.  From the photos, the chin is a bit weak (with excess fat under the chin) as are the mandibular angles and the nose is quite wide.  This combines to create an elongated oval shaped face.  The following procedures would create a more ruggedly handsome face.Chin augmentation, using a chin implant, to add projection to the chin creating harmony and balance to the lower face.  I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy, the lower face looks short, de-emphasizes the lips and allows early formation of a "double chin".  Proper placement of a silastic chin implant adds forward projection to the chin thereby creating harmony and balance to the lower face.  Using the same incision, liposuction can be performed to reduce the fat and further shape the neck.  Excess skin, from below the chin, can also be removed through the same incision.  I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty (requires extensive tissue dissection, bone cuts and placement of metal screws and plates to secure the cut bone segments).  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  In my opinion, you are a good candidate for chin implant surgery.  
Augmentation of the mandibular angles using a dermal filler (jaw implants have too many unwanted side effects IMHO) to add volume, angularity and flare to the jaw line.
Hope this helps.
