Our Goal of modified segmental osteotomy on maxilla accompanied by mandibular anterior subapical osteotomy was to get the best results from patients of bi-alveolar or bi-maxillary protrusion. In this study, cephalornetric and photo (en face, profile) analysis have been compared to define the soft tissue change after surgery. Lip protrusion was efficiently reduced and nasolabial angle was much obtused Although nose was a little widened, it was quite acceptable. Blood circulation on osteotomized segment was well maintained This relatively simple methods could be successfully applied to many patients.
