Can you change the shape of a person's face, square jawline?

Some aging-related changes, such as jowling, can alter the shape of a person's face and cause a square jawline. Some of these changes can be changed with surgery; however changes
related to the underlying bony or muscular structure are not as easy to
alter. It is important to discuss your
concerns with your surgeon, who can then give you a detailed analysis about
what can or cannot be altered.

Depending on the aesthetic goals the face can be changed by manipulating the soft tissue, adding volume by way of fillers or by implants, or by moving the bones by way of orthographic surgery.

The goal of a facelift is to make a person look younger and rejuvenated,
and yet retain natural appearance. In some patients it is appropriate to change
the shape of the face, assuming that is also requested by the patient. There
are various surgical maneuvers that can achieve changes in the facial shape to
create a more esthetic appearance and harmony. Seek out an experienced and
talented surgeon, review his before and after photos of patient that have
undergone similar transformation. In this fashion you will be able to get a
better idea whether this is the type of change you desire.
