With all due respect to my other colleagues posting here about how "technically difficult" it is to repair this problem, I first encountered this problem over 20 years ago when seeing facelift patients of other plastic surgeons. The best "fix" is avoiding the problem in the first place via better facelift technique, but there really is a technically "easy" correction when this problem is encountered.
The soft, mobile earlobe is a really poor place from which to suspend the facial tissues during facelift and necklift procedures. Unfortunately, many facelift surgeons do just that and end up with "pulled" earlobes, widened visible scars in front of the ears, or even regular "hanging" earlobes turned into attached "pixie" earlobes. I was asked to "fix" these by unsatisfied patients, usually very early after their facelifts, when redoing the entire facelift was neither necessary, nor something ANY patient wanted to do. Frequently their own surgeon had already tried to excise and revise the scar, only making things tighter, and ending up with the same problem, only worse. (Your pulled and blunted tragus and "gun barrel" ear canal is another problem, but for another question.)
Frankly, there is a straightforward solution that I perform under local anesthesia which not only addresses the stretched earlobe, but can restore the normal "hanging" anatomy you started with, and leave a thin, non-stretched scar. This is not some magical trademarked procedure, but it involves securing the facial tissues to the periosteum of the mastoid just behind the earlobe so that the (dermis of the) facial skin is suspended from the mastoid fascia, taking all tension off the earlobe. This also serves to support the facial/cheek skin from a fixed, durable structure (mastoid fascia), making the cosmetic results of the facelift "last" longer.
Ideally, this suspension technique that relieves tension on the earlobe should be done at the time of the initial facelift or neck lift surgery, but it can be done at the time of a revision, and this will solve the problem quite nicely. Those surgeons who want to try this out can call it the "Tholen modification!" (just joking--I truly abhor "named" procedures--I'm certain I'm not the only plastic surgeon who has figured this out.)
