Bilateral sagittal split osteotomy (BSSO) is a well-defined process that moves the mandible in three directions of space and moves it into the correct position. BSSO has been described in the literature as a safe procedure. However, it includes some intraoperative and postoperative complications. The most common of these is the bad split. The aim of this article is to present bad splits cases and treatment methods. In our center had made 102 BSSO cases in 2012-2019 and 6 of these include bad split. 5 of these buccal plate fracture on proximal segment, one of these distal segment fracture include condyler process. All cases had managed intraoperatively with screw osteosynthesis and no need for additional precaution like rigit intermaxillary fixation or a prolonged stay. All patient were followed for 1 week, 1month, 6 month and 1 year. None of patient had showed poor function or temporomandibular dysorder postoperatively. Even if a bad split consist of during surgery, no influence final result or postoperative course. Consequently, bad split is not avoidable all time. When treated well the chances of functional success are good.
