How the SMAS Facelift Is Done

Facelift on the Support Structure for the Face

The SMAS rhytidectomy, also known as SMAS facelift, is a surgical procedure that corrects the sagging appearance of the neck and the lower two-thirds of the face. It is performed to change the appearance of sagging skin, excess fat, jowls, and loss of volume in the cheeks. It is less invasive than a regular facelift, which targets the superficial skin of the face, and recuperation is faster.​

The SMAS (superficial muscular aponeurotic system) is the layer of the muscles of facial expression in their own connective tissue envelope. It lies beneath the skin and subcutaneous tissue. It is one of the most important support structures for the face and neck. The manipulation of this anatomic structure changes the appearance of the face and neck.

The SMAS Facelift 

As your facial skin begins to age, there is a loss of elasticity in the epidermis as well as the SMAS membrane. This loss results in sagging cheeks along the jaw bone, creating fleshy jowls and often a double chin. Cheek fat will then sag forward to increase the appearance of the nasolabial folds.

With aging, the SMAS descends on the lower two-thirds of the face and the neck. The front edge of the platysma muscles in the neck is seen and constitutes the "turkey neck" look.

An SMAS facelift counteracts some visible signs of aging by tightening the muscle, removing fat, and trimming excess skin.

An SMAS facelift can correct the following:

  • Sagging in the midface
  • Hollow cheeks
  • Nasolabial folds
  • Jowls
  • Sagging fat
  • Loose skin and fat under the chin and jawline
  • Sagging of the neck

A facelift may remove or reduce the signs of aging but, over time, they will gradually reappear.

Candidates for an SMAS Facelift

You may be a good candidate for an SMAS facelift if you are over the age of 50 and want to surgically correct one or more signs of aging. The outcome will be best if you still have some elasticity in your skin.

You must be healthy and a non-smoker so you will be able to heal from the surgery.

And it's important to have realistic expectations of the procedure. Talk to your plastic surgeon to discuss your expectations in terms of appearance, healing, and recovery.

Risks of Facelifts

The risks of the procedure include the general risks of surgery and anesthesia, such as reactions to medications, breathing problems, bleeding, infection, and blood clots.

Potential adverse events include nerve damage to your facial muscles, pain, numbness, and wounds that don't heal. Some people are unhappy with the outcome due to scarring, irregular contours, or changes in skin color.

Procedure

After you have been prepared for surgery, you will be given anesthesia, which is usually intravenous sedation (IV) and a local anesthetic.

Your face will be marked for the placement of incisions. An incision is made at your temple, above the hairline. It will extend downward along the natural creases of the skin and curve behind the ears.

The facial and neck tissue and muscle beneath the skin will then be lifted and rearranged into a higher position and excess skin will be removed. The skin will be redraped over the face and the incisions will be closed with sutures. Most of the scars will be hidden within the hair and the normal creases of the skin.

The SMAS facelift may take several hours to complete, depending on the extent of the procedure.

You will have a head dressing and drainage tubes after the procedure. You should expect to have some swelling, bruising, numbness. and discomfort for a few weeks. You should be able to return to work after two to three weeks and resume exercise and daily activities after healing is complete.
