What is the Difference Between a Thread Lift and a Suture Suspension During a SMAS Facelift?

I am always impressed by the fund of knowledge that is shown by the people asking questions on this site!

There are different facelift techniques, all seem to handle the firm tissue under the skin (the SMAS) a little differently. You should leave the decision for facelift technique up to your surgeon. Ask to see their patient photos and talk to their former patients before making a decision. Check on the credentials of your surgeon. Both plastic surgeons and facial plastic surgeons are trained in facelift surgery, however, the training of facial plastic surgeons focuses entirely on the face. 

Since you asked about threadlifts, you should know these were taken off the market. This procedure involved the placement of barbed permanent sutures (like fishing line) under the  skin and then the skin was pulled up to hook on the barbs. There were problems with extrusion of the sutures and the results only lasted about 6 months.

Thread lifts are basically Sutures used alone with out a lifting procedure in my experience and those of many other plastic surgeons "thread lift" do not have much longevity and not worth the effort. They may look great for months but not years.A SMAS lift in general refers to any facelift technique that tightens the SMAS layer using suture suspension along with the overlying skin in a more youthful position making you look younger. Specifically, the SMAS face lift does its magic by lifting and tightening the jowls, neck, and cheeks to a more youthful position. These techniques generally produce more natural and long-lasting results than the “skin only” face lifts, and now considered by most board certified plastic surgeons as the most preferred method.

A thread lift is a barbed suture repair and if done alone will last weeks to a few months only. It is not as secure as direct suture suspension during a SMAS facelift procedure. I would be quite concerned about doing a thread lift suture suspension only of the SMAS. It is much better to use direct sutures with permanent sutures if performing  a  suspension or SMAS plication while doing a facelift to give you increased longevity.
