Abstract:
When paranasal deficiencies are not accompanied by occlusal alterations, mobilization of the maxilla via Le Fort I osteotomy may not be justified. In this preliminary, report for the first time is presented a U-shaped osteotomy (USO) that mobilizes anteriorly and/or superiorly the maxillary bone surrounding the pirifom aperture. Advantages and indications of this new procedure are discussed.
