The concept of beauty is central to all human cultures regardless of race, age and sex. Physical appearance has always played a significant role in the development of self conceptualization and self esteem, in the establishment of interpersonal relationships, in employment opportunities and in the quality of life. Dentofacial deformities affect approximately 20% of the population. Patients with Dentofacial deformities may demonstrate various degrees of functional and esthetic compromise. Many patients with Dentofacial deformities can benefit from corrective orthognathic surgery. The specific therapeutic goals vary from patient to patient. These goals are directed towards correction of specific musculoskeletal, dento osseous, and soft tissue deformities. Several factors, presenting either collectively or individually, may indicate the need for orthognathic surgery. Proper patient selection remains the primary factor in successful treatment outcome.
