Does Lifting and Tightening the SMAS Cause Cheeks to Flatten?

A doctor told me that tightening the SMAS causes the cheek to flatten. Is this true and if so how do you avoid that? Also, if you just do a composite necklift which address the lower third of the face is the SMAS involved?

SMAS plus adding volume to the cheeks

No, SMAS should not cause the cheeks to flatten. But keep in mind that the cheeks are not addressed with lifting during SMAS. If your cheeks need to be rejuvenated, that will require add volume to them with fat, Sculptra or fillers.

Well-Performed SMAS Does Not Cause Cheeks to Flatten

During an SMAS lift, the muscle and skin are lifted. If the cheekbones are already flat, fat from the lower face can be brought upward to fill out the cheekbones. Or, fillers can be used later. A lift will not make cheeks look flatter if it's performed well. Be sure to find a facial plastic surgeon who has extensive experience in facial anatomy and aesthetics. I hope this helps.

SMAS facelift and cheek volume

A SMAS facelift can add volume to the cheeks if the person needs it.  The facelift can also be performed without lifting the cheeks in the case of a low SMAS lift.  The statement that it does not elevate the cheeks is not true but if done correctly, you can avoid adding volume to the cheek or it can be performed to volumize the cheek. Hope that helps.

Lifting the SMAS will add volume to your cheeks. Injecting fat can help too.

It’s an excellent question. The SMAS is a layer of connective tissue that envelops the face and connects to the platysma muscle in the neck. As we age the SMAS and other facial tissues loosen and descend. When you re-elevate the SMAS you actually return these tissues to their original location. A SMAS facelift will restore volume to your cheeks, elevate your jowls, and improve the appearance of your neck.

As we age, we lose volume in our face. This volume can be improved by lifting the SMAS, but it’s often beneficial to add more volume with fat. Fat can be harvested using liposuction and transferred to the face with a small injection cannula. The volume restoration can be dramatic and adds a youthful appearance that goes beyond what a facelift can do alone. Fat can be injected into many areas within the face including the cheek area (malar area), the nasolabial fold, the junction between the lower eyelid and the cheek, along the superior orbital rim, as well as the temporal area.

Your surgeon will help you determine which treatments will work best for you.

SMAS Facelifts Augments Cheeks

Just the opposite of what you were told. The SMAS lift re-positions your cheek fat over your cheek bones to augment, not flatten it. A composite lift is losing favor among many plastic surgeons due to the very long recovery time. It moves tissues at a deep plane level close to the bone in many areas lifting all tissues more superficial including the SMAS. As this is not the location for tissue aging it makes less sense than turning back anatomically the aging process

SMAS Facelift and Cheek Flattening

The use of the SMAS does not cause the cheek to flatten.  The use of the high SMAS procedure will actually increase the fullness over the cheekbones and help to restore the heart-shaped face of youth.  The use of the SMAS will also allow for for improvement of the lower face and neck.

SMAS and cheek flattening

It depends upon where the muscle is sutured. The important thing, if a patient has any qualms about which area of the cheek would be tightened and flattened, is to discuss them with her plastic surgeon.

SMAS Elevation Creates Voluptuous NOT Flat Faces.

It is skin tightening across cheeks that causes flat faces.  A advanced technique SMAS Facelift should uses the SMAS layer as a vector to carry the facial fat to more superior positions, enhancing cheeks, periorbital, and cheekbone regions.  This result actually looks more full and voluptuous, with little tension applied to the skin for the actual lift.  Facelifts that rely upon tension on the skin move little of the facial fat, and when pulled over structures such as the cheekbones, actually make structures appear flatter, due to the taught skin draped over them.  While these types commonly performed skin facelifts, results are disappointing after 3-6 months when swelling subsides, and little change is seen.  Due to the skin tension applied to perform such facelifts, incisions and resulting scars are usually obvious and such patients generally look "pulled".

SMAS cause cheeks to flatten

As the majority of the expert posters have stated NO! The SMAS if done correctly can not flatten the cheek, just the opposite happens. Please re think the question.
