Is midface suspension the same as a subperiosteal lift?

A midface lift can be done with SMAS manipulation or via the subperiosteal plane.  More typically it refers to elevating tissue in the subperiosteal plane and suturing it up to temporal fascia.  However, the SMAS approach has shown more natural results with quicker recovery.  

Hello and thank you for this question. To answer you directly, these are different procedures.
A subperiosteal lift is an older facelift procedure targeting the mid- and upper-face which has since been replaced by newer techniques which offer greater patient safety and comfort, better results and faster recovery times. During this procedure, your doctor will lift the skin off the bone and reposition it in order to achieve the desired outcome.
The suture midface suspension facelift — or threadlift — is a minimally-invasive alternative. The technique lifts and anchors facial tissues using sutures applied through 1 centimeter incisions. This technique has several advantages such as its short recovery time and price, however, it is not a long-lasting procedure and can have unique complications including suture breakage.
To find the procedure best suited to your individual needs, schedule an in-person consultation with a local, board-certified facial plastic surgeon in your area. Good luck!- Elbert T. Cheng, MD
