Orthognathic Surgeries are being carried out in adults who needtreatment for their dentoskeletal deformities. A good surgicalplanning should be there when moving forward to Orthognathicsurgeries. The Conventional Orthognathic Approach (COA) hasthree phases- Pre- Surgical Orthodontic Phase, Skeletal SurgicalCorrection and Post- Surgical Orthodontic Phase. An alternatesurgical approach came which was called as "Surgery First Orthognathic Approach" (SFOA). The rise of SFOA even though showed some controversies, has lately became popular among Orthodontists. The SFOA bypasses the Pre- surgical orthodontic phase and directly enters to the skeletal surgical correction phase. By this there's a reduction in treatment duration and provides earlyimprovement in the facial esthetics. In this book, a proper understanding of treatment planning and procedures involved will be discussed in detail.
