Chin and Cheek

Chin and Cheek Augmentation (Injection or Implant)

Chin and cheek augmentation is a frequently performed procedure to help balance a face which is done by injection or implant placement. Injection is a safe and non-invasive method. The procedure involves injecting filler into precise areas in order to increase the length, width or projection of chin and cheek. Results last for 6 months to one year depending on the product used.

Another method is using facial implants that provide a permanent and predictable result. The implants used for these procedures are made of either a solid or semi-solid material. Dr. Varasteh Kia will recommend which type of implant is best for you and fit with your facial structure.

Chin augmentation surgery is usually performed with general anesthesia. In this surgery, incisions are made inside the mouth or on the underside of the chin. Chin augmentation surgery is often paired with nose surgery to achieve a more harmonious appearance.

Cheek augmentation surgery is also usually performed under general anesthesia. When paired with a facelift, eyelid lift or forehead lift, the cheek implants can be inserted through incisions made for those procedures. Otherwise, incisions are made inside the upper lip or lower eyelid.

Fat Injection

Fat injections can be an effective way to reduce wrinkles, diminish acne scarring and regain a more youthful appearance. By injecting human fat harvested from your own body, cosmetic surgeons enhance facial fullness, fill deep creases, soften facial creases and wrinkles, plump lips, and build up shallow contours.
Fat grafting usually involves harvesting fat from one part of the body, washing / purifying it, and the carefully re-injecting it with specially designed needles into the areas requiring augmentation. The procedure may need to be repeated several times to achieve the desired result.

Main advantages of fat grafting include:

  1. A long-lasting result contrary to the synthetic resorbable products
  2. Prevention of granuloma development or allergic reaction which could be seen with permanent fillers
  3. A natural consistency
  4. Improvement of cutaneous and subcutaneous trophicity
  5. This technique could be proposed to almost all patients presenting enough fat tissue.

On the other hand, disadvantages of autologous fat grafting include:

  1. Its complexity of use, requiring a more important learning curve with regard to the prepared products
  2. The morbidity and the necessity of donor site, that sometimes could not be enough
  3. The unpredictability of the remaining volume by partial uncontrolled absorption of the fat transplant

It is hypothesized that adding Platelet Rich Plasma-PRP to fat preparation may be a reliable way to bring appropriate nutrient at the early moments of transplantation to improve fat survival and render the result more predictable. PRP releases the native growth factors in their biologically determined ratios at the treatment site. Released growth factors stimulate angiogenesis, cell differentiation and proliferation leading to the reconstitution of the tridimensional matrix that allows the rearrangement of adipocytes into the correct 3D organization. Providing a blood supply on which fat cells are extremely dependent creates an optimal in vivo environment to promote fat implantation.
