Plastic surgery patients have many options for sunken, hollow cheeks and the midface area. Although age and sun damage are the biggest contributing factors, many patients on HIV medications have a condition called facial lipodystrophy, which also causes hollow cheeks. Other patients develop hollow underneath the eyes from weight loss.
Regardless of the exact method, the aesthetic treatment is for cheek indentations and eyelid hollow is augmentation. Fortunately, one has many options to add volume to sunken cheeks. More temporary injectable fillers, such as Restylane, Juvederm, and Radiesse, last several months by augmenting the skin. The cosmetic facial treatments must be repeated, but injections are simple office procedures with little downtime. Injectable fillers are more affordable.
Another injectable solution is Sculptra. It's a material which is injected much deeper into the face and stimulates fibrous tissue over time. Results are not immediate, but rather develop months after treatment, but last much longer. Patients usually require more than one treatment for the desired cosmetic effect.
The more popular solution for injection is fat from you own body, performed either under local, IV sedation, or general anesthesia. Fat injections have the possibility for long-term natural results. Some touch-up injections may be necessary, but may be performed in the office.
The most permanent solution for the cheek is enhancement with a silicone implant. Cheek augmentation with implants is performed under IV sedation or general anesthesia via a small incision inside the mouth. There is more swelling and bruising as compared to the other techniques, but results last much longer.
Lastly, a combination of various volume enhancement solutions may be performed at the same time with a surgical lift of the mid face and cheek area.
Based on this picture, you have both loss of volume in the area and sagging of the cheeks. You may benefit from a combination procedure, performed at the same time or delayed by several months. Speak with a facial plastic surgeon to discuss cheek augmentation to find a cosmetic treatment which is appropriate for you.
