1 year after neck lift I have submandibular gland protruding?

Although no photos are submitted, it is likely that the submandibular glands were prominent before the facelift but in fact were camouflaged by the excess skin and sagging. The operation to remove these glands is extreme and generally not recommended. Sometimes the glands can be lifted slightly by judiciously placed sutures, but this is not normally done with the usual facelift. In addition to inherited tendencies the contour of the neck is because of the laxity of the muscles and skin. These are tightened causing the patient to feel "fullness" in the floor of the mouth after facelift. This will improve with time. There is an anatomic limitation on how much these can be lifted and therefore how much the neck angle can be improved.

is not 'minor' surgery and there are risks to your nerves when removing it.  If your surgeon is a whiz with removing that gland, then it may be minor in his/her hands.  But most surgeons don't even touch it due to the risks potentially involved with removing it.
