Rehabilitation of the paralyzed lower lip.
There is a continuum of smiles from the one of the reserved Mona Lisa to a full dental smile where there is maximal exposure of teeth and full triggering of all the major and minor smile muscles. The ramus mandibularis paralysis is more obviously noted in the full dental smile. The ramus mandibularis paralysis is best corrected through a technique of wedge resection of the lower lip with a segmental sling to the nasolabila groove.
