The soft-tissue chin may become ptotic following surgery in this area. The
mentalis muscles which are responsible for proper central lip motion and chin
point position may be affected. The mentalis muscle origin may require
resuspension at a proper level. This reattachment may be performed by means of
an intraoral approach. Non-absorbable sutures are used to hold the soft-tissue
chin upward. The exact method involves placing drill holes through the alveolar
bone, into which sutures are passed. These sutures are then placed through the
lower mentalis muscles and tightened. Chin and lip position may be corrected in
certain cases. Ancillary procedures are required to correct vestibular scarring
and submental scars.
