Flat face from one side - solutions? (photos)

Considering that your photos do not show much in-person evaluation with a board certified plastic surgeon is recommended. 

The photos provided are not optimal, but do suggest flattening of the face in the cheek areas. If so, this should be rather easily remedied with the use of a volumzing filler, such as Voluma XC, which would be my choice in my Upper East Side Manhattan practice or Stylage XXL, which would be my choice for this in my Israel satellite facility, where a far greater number of regulatory agency approved volumizing fillers are available. Inexperienced, novice injectors trained only to use plain Juvederm or Restylane for treating simple smile lines might suggest the use of these materials for the cheeks. However, the lift and shaping obtained from these and the duration of the effect are unlikely to be satisfactory. So, since nonsurgical facial shaping and contouring is an advanced injection technique, be sure that you seek consultation and treatment by a board certified aesthetic physician. And make sure to ask to see his/her before and after photos before agreeing to proceed.  Best of luck to you.

Facial sculpting, contour, volume and symmetry of the face can be created with well-placed fillers (Voluma, Radiesse, Bellafill) and Sculptra. Implants or fat would be alternatives. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer

Your pictures are not the best to make an assessment as they just show one side at a time. But it appears that it is combination of both cheek and jaw deficiency for which cheek and jaw implants would provide the best long-term solution.

The face is a three-dimensional structure, so  a full set of facial photographs are required to make a determination about a surgical procedure  such as  cheek Implants. When patients have a flat maxilla/ cheek on either one or both sides, consider cheek implants for a permanent augmentation.  Cheek implants are composed of  silastic, and are manufactured in a large variety of sizes and shapes, and can be custom carved when necessary to match patient's unique anatomy.  For more information, many examples including diagrams of the implants themselves, please see the link and the video below

 Hi, I have performed many facial shaping procedures using dermal fillers, facial implants (cheek, chin), liposuction and/or facelifts for over 30 years. According to the beauty principles that I've followed for the past 30 years, men look chiseled and handsome with angularity in the cheeks, chin and mandibular angles.  The attached photos hide too much of your face to allow accurate evaluation. The cheeks are flat when the required bone volume to make them angular is lacking.  
 Non smiling photos of your face from the front and side would help in the evaluation.  You can e-mail these privately if you prefer but the ones included do not show enough of your face to help in the evaluation.  In general terms, the following procedures can create a more ruggedly handsome face.
The Cheeks can be augmented with cheek implants or using a dermal filler to add angularity to the cheeks and mid face.  
Hope this helps.

I can't tell from your photos.  Generally, everyone has some asymmetry.  If your asymmetry is pronounce, then options typically will include cheek implants or facial fat transfers.  Best wishes.
