Need solution for sunken temples (Photo)

Great question! Your best option to restore the temple contour and fill the volume defect is to have filler placed in the area of concern. In general there are two types of filler, synthetic off-the-shelf nonpermanent fillers (hyaluronic acid) such as juvederm or restylane, or semipermanent fat which is harvested from an inconspicuous area of your body, processed and injected into an area. Depending on the area the fat is transferred to, a variable amount of the fat will survive and can be anywhere from 0% to as high as 70%. Given the area of concern in your case is the temples, I would recommend synthetic filler which can last up to 18-24 months depending on the particular filler brand/type chosen. Although fat grafting (transfer) is an option, we know from published experience (as well as my own personal experience) that fat transferred to the temples typically has a low percentage "take" as most of the fat transferred is simply reabsorbed by the body after several months. Thus the results with fat transfer will likely be much shorter lived and definitely more unpredictable than synthetic fillers in your case.

Thanks for the questions. 
Fat grafting can be a good solution for restoring volume to the temples. Usually I have seen this in older patients who have lost volume due to fat atrophy over time. Fat grafting has the advantage of being a relatively straightforward procedure, done in the office, and it is your own tissues. The downside is that it will be more expensive than a single round of fillers, and it may take multiple rounds of grafting to get the result a patient desires. 
You may be a good candidate, but an in person exam is needed. Photos may not show the true extent of atrophy or lack of volume in a region. 
Pricing varies widely based on the physician performing it as well as the location. I often advise patients to 1. choose a qualified surgeon to do this procedure (not just any physician or PA who states they do it), and 2. do not let price be a determining factor. One place to not go cheap on is someone's own body!

Fillers and fat can accomplish the same thing, adding volume. However fat not only provides volume, it also adds stem cells which have huge benefits for your skin and surrounding tissue. Discuss these with your plastic surgeon. With regards to cost, it may vary between practices. See a few doctors and compare. Questions to ask include what donor site is used, how the fat is prepared, and how it is injected under the skin. I wish you the best!

Dear Dottyliu,the cost of surgery depends on a lot of factors (type of surgery, number of treated areas, anesthesia fee, surgeon, facility fee, city, etc.). It would be the best to visit or call plastic surgery offices and ask for a price.Daniel Barrett, MD, MHA, MS

Temples can be improved with fillers (radiesse, voluma) or sculptra. Fat is an alternative. cost will vary. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer
