Abstract

Bimaxillary orthognathic surgery has many indications when correcting dentofacial deformities. There is added complexity in achieving clinically accurate results when simultaneously operating on both the maxilla and the mandible. It is crucial to have precision in clinical evaluation, presurgical planning, and execution of surgery to ensure ideal clinical results. Moreover, the surgical sequence of bimaxillary surgery can have clinically relevant effects on ease of surgery and accuracy of planned outcomes. Bimaxillary surgery can be completed in two different surgical sequences: maxilla-first or mandible-first. The traditional method repositions the maxilla first and then the mandible. However, internal fixation with plates and screws allows the mandible to be operated first. Either surgical sequence can produce accurate results if adequately planned and executed. This chapter discusses how the sequencing of double-jaw surgery can reduce surgical error, make surgery easier, and improve patient outcomes.
