Do a mentalis muscle resuspension at the same time as submental chin implant or don't do this at the same time?

I agree with Dr. Eppley.  The mentalis muscle resuspension and chin implant must be in harmony.  This best achieved from an intraoral approach.

If you are going to do a mentalis resuspension it should be done at the same time as a chin implant. But because a mentalis suspension is a superiorly based procedure it can not be done very well from a submental approach. It needs to be done from an intraoral approach to be truly effective. A menrtalis muscle sag is caused by loss of the attachment right below the depth of the intraoral vestibule.
