Skeletal malocclusions are the result of variation in the relationship between skeletal, dental and overlying soft tissues. Management of these malocclusions in adults requires orthognathic surgery in combination with orthodontics. Until 1960s, surgeons and orthodontists worked independently to correct dentofacial deformities. Thereafter, the conventional approach for correction of severe dentofacial anomalies was introduced which consisted of three stages (presurgical, surgical, postsurgical). As treatment with conventional orthognathic surgery involves a prolonged time period, surgery first orthognathic approach (SFOA) was introduced in which orthognathic surgery is done first followed by orthodontic treatment for alignment of the teeth and settle the occlusion. By performing surgery first approach, Regional Acceleratory Phenomenon (RAP) is initiated which is an important factor in reduction of treatment duration in SFOA. This article intends to provide an overview of the history, indications, advantages, disadvantages, stability of SFOA. Keywords: Skeletal malocclusions, Conventional orthognathic surgery, Surgery first orthognathic approach, Regional acceleratory phenomenon.
