Abstract:
The soft tissue profile changes resulting from double-jaw surgery (maxillary advancement and mandibular setback) and mandibular setback alone were evaluated. The measurements were evaluated on the preoperative and postoperative cephalometric radiographs of 24 skeletal Class III patients. The results demonstrated significant correlations and suggested that the soft tissue ratios seen in double-jaw surgery were similar to those in mandibular setback surgery alone, with the exception of the changes in nasal tip projection and the upper lip area.
