Does the surgical method for a forehead lift vary depending on the degree of sagging?

I'm looking into forehead lifts, and I've noticed there are various surgical methods.

It seems the method of fixation—whether endoscopic or incisional—varies depending on the degree of sagging. When I go for a consultation, I think I'll need to ask specifically about the fixation and surgical techniques. Does an endoscopic forehead lift have a shorter duration of results than an incisional one?

If so, would an incisional method be better even if the sagging isn't that severe? I'm curious...
