A regular lower facelift might reposition the skin in such a way as to make the earlobe more attached. But that is a more brutal surgery ( lower face is peeled and skin repositioned so sag is at the edges and cut off-- not stretched tight) with longer heal time than my guess, which is injectible fillers around the jaw to give a plumper, manlier outline. Then the plumpness butts up against the earlobe and obscures it to give an illusion of attachment. You can look for profile pics to check. Men do get necklifts for turkey neck. The giveaway is a little scar right behind the bone of the chin, underside where there is a natural hollow, that can show for months.

edit: watching his presser where something big falls and he completely turns his head to his left--the right lobe does look attatched, the left one not.
