Lip Augmentation with SMAS Implant

Lip augmentation with a SMAS implant involves removing excess tissue of the superficial musculoaponeurotic system, and then shaping and positioning it in the lips to add volume. This type of lip plumping is only performed during a sub-SMAS facelift surgery. The SMAS separates the facial skin from facial muscles and is comprised of natural fat, collagen, and fibrous tissue. SMAS grafting to enhance the lips produces immediate and long-lasting results and very little downtime.

About the Procedure

Last Updated: 07.28.2021

During a standard biplanar rhytidectomy (facelift), excess tissue of the superficial musculoaponeurotic system (SMAS) can be harvested, reshaped, and positioned in the lips for augmentation purposes. The SMAS is located between the deep skin and muscles of the face. It is made up of autologous collagen, fat, and fibrous tissue. Because it is taken from the patient, it is completely biocompatible and therefore does not cause infection, rejection, or other adverse effects such as with a lip implant. During a facelift, a board certified plastic surgeon can grasp the SMAS with forceps, separate it from the fascia, and then trim it with surgical scissors. It is excised from each side of the face in a single long strip and placed in a sterile saline solution while the facelift is completed. Then, it is reshaped as needed to for the patient’s upper or lower lip properly. Next, small stab incisions are made into each corner of the mouth, and then, a tunnel is created from incision to incision. Finally, the SMAS graft is pulled into the lip via the tunnel. The incisions in the oral commissures are closed with dissolvable sutures, thus completing the procedure. As this surgery is only performed during facelift operations, recovery is only a small part of the larger picture. The average cost for a facelift surgery in the United States is about $8000. Additional costs for SMAS grafting varies depending on location, surgeon, and other factors.

The goal of a lip augmentation with SMAS implant is to plump lips for a more youthful appearance.

Recovery Notes

Initial recovery from a SMAS lip implant can range from 1-2 weeks. Most patients will need to spend at least 3 days away from work for recovery. Exercise and strenuous exertion should be postponed for 2-4 weeks. For the first week after surgery, only consume soft foods that require minimal chewing. Take prescribed antibiotics and use prescription ointments as directed by your doctor.

Ideal Candidate

The ideal candidate for a lip augmentation with SMAS is already receiving an SMAS facelift who is also looking to achieve lip fullness, projection, and eversion.

Not Recommended For

Lip augmentation with SMAS implant is not recommended for candidates who are not interested in also having a facelift procedure, have infections in or around the mouth, lupus, blood-clotting diseases, diabetes, or smokers.

Side Effects

Side effects from lip implants may include bumps, lumps, infection, migration, asymmetry, bruising, bleeding, and swelling. If SMAS implant is placed too superficially it can lead to a visible or palpable implant and possible extrusion.
