I suspect the main reason why 3 surgeons have recommended SMAS facelift while only 1 surgeon has recommended deep plane facelift is that the surgeons will recommend the procedures they are most comfortable performing. A much smaller fraction of facelift surgeons perform true deep plane facelift surgery. It wasn't until the last decade (2010's) that more modern techniques of deep plane facelift surgery, such as extended deep plane facelift, were described and it will be even longer before those techniques become adopted more widely and, ultimately, taught to surgeons during residency and fellowship training. In my experience, the results achieved from extended deep plane facelift are much more significant than traditional SMAS facelift. As far as pros and cons, the risks are the same with both procedures. Cost of deep plane facelift is usually greater. The procedure simply takes more time and skill to perform. Overall healing time may be shortened with deep plane facelift. However, I have not seen any studies that prove healing time, yet. As of now, this is only expert opinion. Incisions are similar and, in some cases, deep plane facelift incisions may be shorter. When performed correctly, it is my opinion that the results of extended deep plane facelift are more significant. Deep plane facelift is more effective for the midface, nasolabial folds and central neck. With that being said, in my practice I still occasionally offer traditional SMAS facelift to patients with less facial aging, especially those with aging effecting primarily the neck. I hope this information is helpful. Kind regards, Dr. Harmych
