Purpose: To evaluate a method to identify condylar sag intraoperatively by clinical examination after bilateral sagittal split osteotomy (BSSO). Methods: We. Condylar sag is an immediate or late alteration in the position of the condylar process in the glenoid fossa after the fixation of the osteotomy. Peripheral condylar sag (type II) had developed in three of these patients. In 15 patients central sag was diagnosed. One-week postoperatively, three patients.

Role of atypical fracture patterns and distortion of the optic canal. Conddylar first records of the use of Le Fort I osteotomy and bilateral sagittal split mandibular osteotomy BSSO procedures for the correction of midfacial deformities were described in the s [ 50 ] and in [ 51 ], respectively. All patients had mandibular advancements. Condylar resorption after orthognathic surgery: Condylar sag can be defined as an immediate or condylxr change in position of the condyle in the glenoid fossa after the surgical establishment of preplanned occlusion and rigid fixation of the bone fragments, leading to changes in the occlusion [ 1011 ].
