Can a neck lift be done without cutting under the chin? (Photos)

Good question. I have performed thousands of lifts with and without the incision under the chin and I do believe when warranted the added chin incision allow for better results. The incision under the chin allows for chin lipo and a platysmaplasty (tightening of the neck "turkey bands" muscle).  I do see the bands on your lateral view. You will have a better neck with a lower facelift but an even superior result with an added incision under the chin to perform the above.  

In cases without significant muscle looseness, it's possible adhesive what you've mentioned without a submental incision in my experience.
