Orthognathic surgery has become more prevalent today in the treatment of adult patients with facial deformities. Currently, the cephalometric norms used for assessment of the deformity and the treatment planning are those for the Caucasian population and thus all patients, regardless of race, are evaluated by these established standards. In our work, surgically useful rectilinear cephalometric norms for the diagnosis and treatment planning of orthognathic surgery in adult Central Indian population were evaluated for its practical implementation in the treatment of the facial deformities. These racial differences are evident in our work and can be of clinical importance while charting out plan for the orthognathic surgery.
