In the evaluation of the
beauty and functional integrity of the lower face, the oral cavity, teeth,
mandible, maxilla, and the size and position of the tongue are important. The
tongue locates forward and is larger than normal in prognathism, in which the
jaw protrudes from the skull. It is not clear whether an enlarged tongue causes
the open bite, protrusion or dental arch misalignment, or is a result of them.
Here, we report two patients with mandibular prognathism and relative
macroglossia, which were treated by mandibular setback surgery using a
bilateral sagittal split osteotomy (BSSO) and excision of the tongue. This
procedure achieved aesthetic improvement of the face and dentition.
