Introduction: The bilateral sagittal split osteotomy (BSSO) is preferred by most surgeons to correct mandibular sagittal skeletal discrepancies. However, studies on its stability are controversial. Aim: This study evaluated the different factors associated with long-term stability, such as quantity of mandibular advancement, type of fixation, utilization or not of surgical splints, condylar position, and others. Conclusion: Based on the literature, it was concluded that the magnitude of mandibular sagittal movement should be less than 10mm; rigid fixation should be chosen instead of semi-rigid; the utilization of splints should be avoided or used for a short period; and pre- and postsurgical orthodontic treatments are essential to obtain satisfactory results.
