My doctor says he will operate with a deep plane endoscope, is such a thing possible?

The endoscope is a good method to lift the midface and forehead. Both of these require repositioning tissue - brows and cheeks- but don't require skin excision. Although one can use and endoscope to help with the deep plane lift skin incisions and excision are still required to treat the jowls and neck well. If one is going to need to open the face and neck anyway not much advantage is gained by using and endoscope. So, in sum if you are only needing the midface and forehead endoscopic procedures are good but if you need a jowl neck lift you will usually need and open facelift procedure.

Endoscopic forehead lifts have pretty well been shown not to do much. I think the same can also be said about midface lifts. Personally I don’t care for the lip lift. If you look at pictures online you’ll see that a lip lift can drag down and distort your nostrils. It sounds like you’ll be swinging a lot of extra money for things that I don’t think are worthwhile at all
