Abstract

The aim of the case reportwas to evaluate the dentoskeletal and soft tissue changes following bilateral sagittal split osteotomy (BSSO) for mandibular setback using cephalometric composite analysis.Pre-surgical and postsurgical lateral cephalograms were digitized and the measurements were assessed with high quality digital imaging software.There was significant anteroposterior setback of the mandible. The mandibular body length decreased while mandibular ramus height increased postsurgically. Similarly anterior facial height increased, posterior facial height decreased and mandibular plane angle increased after the surgery. Thedistance from the dorsum of the tongue tothe roof of the mouth decreased.Similarly,the position of the tip of the tongue relative to lower incisors was also reduced postsurgically.BSSO with mandibular setback was successful in achieving drastic changes in linear and angular cephalometric measurements postsurgicallythereby improving the patient’s facial profile and balanced occlusion.
