Deep Plane DAO Release - are there any known long term complications?

The DAO or depressor anguli oris is a muscle which functions to depress the lateral lip and corner of the mouth. So, in situations of a severe marionette line/ depressed corner of the mouth, such a maneuver can be helpful in improving the aesthetic result. Usually, there is some degree of muscle re-connectivity in the months after the procedure, so major long term functional or aesthetic detrimental effects are expected.

At 55 there is a good chance that a facelift would be worthwhile. I’ve never done DAO rri ease and can’t imagine it’s worthwhile. Also deep plane facelifts are no better than standard facelifts. Go on some consults with surgeons in your area. Whatever you do don’t let them talk you into fat transfer to the face. I know it’s all the rage now but it’s an absolute waste of money.
