The surgery-first approach is based on initially improving facial aesthetics, which is usually the patient's main complaint, and then moving on to the second stage of occlusal movement and alignment. This literature review aims to evaluate and compare the findings regarding the conventional protocol. and the suggestion-first protocol. A MEDLINE search. Inclusion criteria were 1) human study and 2) orthognathic surgery with surgical-first approach or equivalent, and 3) three-dimensional planning with virtual flow in a suggestion-first approach. After an evaluation of the contemporary literature, it was concluded that this approach is positive when related to treatment time, patient's quality of life, post-surgical orthodontic time and occlusal stability. Overall, the SFA achieved optimal results comparable to the conventional protocol regarding treatment success.
