Orthognathic surgical corrections of deformities and defects are performed to establish normal functional relationships between osseous, muscular, and contiguous structures. At times, aesthetics will be improved, but this psychosocial improvement is an additional benefit as long as correction of the functional aspects of the skeletal deformity constitutes the criteria for surgical intervention.
正颌外科手术对畸形和缺损进行矫正，以建立骨骼、肌肉及相邻结构之间的正常功能关系。有时，美观度会得到改善，但只要以矫正骨骼畸形的功能方面作为手术干预的标准，这种心理社会层面的改善就是额外的益处。
