Opinions on What is Happening to my Chin Scar - 2nd Surgery Post Op

The bunching that you see at the ends of your chin scar after a Facelift is called a dog ear. It is excess skin that was not removed or tightened during the Facelift chin scar revision and has the shape of a dog's ear.

You are very early after your revision. Massage and time should lessen the appearance-give it at least 3-4 month possibly 6.

The reason it occurs is that the surgeon did not want the scar of the incision to pass outside the jaw line where it would be visible.

Revision may be possible by curving the incision back towards the underside of the jaw if revision is necessary. Alternatively revision may require further tightening of the excess skin from the Facelift incision around the ear, but this might pull the scar into a visible position.

I do not believe fat is causing this and fat removal alone will not help-there is skin excess that must be addressed if massage does not help

As you know from experiencing the healing from your primary lift, there are changes going on for months.  Revisions take even longer, as the surgeon was working on scarred tissue, not virgin tissue.  Ask about massage, silicone containing scar gels and ultrasound treatment.  These things are proven effective.
