Modified Rotational Anterior Segmental Osteotomy for Prevention of Common Complication (Aged Appearance)

Although anterior segmental osteotomy (ASO) is powerful procedures in treating the patient who has bimaxillary dentoalveolar protrusion, there is significant change in all soft and hard tissue parameters. Soft tissue changes in response to ASO can have a deleterious effect of an aged appearance. To prevent this aged appearance, the authors tried to rotate the maxillary anterior segment rather than simply posteriorly translating the segments. The application of a clockwise pivot rotation method during ASO can prevent overcorrection by controlling the degree of setback of the piriform aperture, and it can also affect convexity of the facial profile.
