With due respect to the doctor who suggested "Endoscopic Mid Face Suspension Lift with buccal fat pad suspension," either you misunderstood what is being recommended, or he misspoke. If he didn't, then this is an example of using lots of "medspeak" to sound technical, advanced, and well, AMAZING! (Actually, that should have read "misleading.")
First of all, if you have loose wrinkled skin in need of a facelift/necklift, an endoscope is not the way to go--you need to have the facial skin cut, lifted from the underlying structures, and the support layers (SMAS--the Superficial MusculoAponeurotic System, which essentially is the facial fascia or "gristle" layer continuous with the temporal fascia and platysma muscle in the neck) tightened so that the jowls and malar fat pads are repositioned to their previous youthful position, the excess skin excised, and the remaining loose skin redraped, smoothed (neck and jawline) and tightened--not too much, but just enough to restore youthful appearance without excessive and unnatural tautness. Loose skin removal after redraping and repositioning requires skillfully-placed and hidden incisions so that the excess skin can be removed and the jowls eliminated.
That can't be done with an endoscope!
And if you don't need to have the excess/loose skin removed via incisions (and well-hidden, beautifully-healed scars), then you probably don't need a facelift/necklift, especially to "suspend buccal fat pads!"
This sounds like a limited-incision midface lift via endoscope without skin excision, but it's not the buccal fat pads that are being suspended (if this is what the doctor really meant, then he's got his anatomy descriptions wrong IMHO), it's the malar fat pads, and the SMAS near the modiolus region of the face to elevate and retighten the jowl area. Either that, or it's just marketing medical gobbledygook. And a potential waste of your time, money, and expectation!
A properly-performed facelift will "last" for differing periods of time in different individuals, each with unique genetics, collagen, and elastic content, not to mention weight gain, smoking, or sun exposure habits. An exact amount of time is impossible to predict, but a skillfully-performed facelift/necklift should "last" in the range of 6-10 years for most individuals. What is being pitched to you might make subtle improvements (if there are no complications), but they probably won't last more than a year or two (like many Threadlifts, Lifestyle Lifts, QuickLifts, etc.) And I'll bet he's charging over $10,000 for what should be much less!
I've often wondered if I should call my facelift operation the "Tholen Tissue-Tightening Dual-plane SMAS-securing fat sculpting facial rejuvenating Power Lift." (Darn, I left out "Laser-assisted.") Wouldn't THAT be special?
I think you are right to feel that what is being suggested is somehow not passing muster. I'd suggest consultation with one or more American Board of Plastic Surgery-certified plastic surgeons in addition to the ENT (facial plastic) surgeons you have spoken to. You should have better information, or at least more complete and anatomically-sound, recommendations. Best wishes! Dr. Tholen
