Condylar Position Changes and TMJ Functions After BSSO Mandibular Setback, Low Medial Cut.
Maxillofacial Abnormalities, Mandible Prognathism, Skeletal Malocclusion
About this trial
This is an interventional treatment trial for Maxillofacial Abnormalities focused on measuring mandibular setback, low medial cut, condylar position
Eligibility Criteria
Inclusion criteria: Age of the patient between (18-60) years Patients in need of mandibular setback using bilateral sagittal split osteotomy. All patients are free from any systemic disease that may affect normal bone healing. Patient with facial deformity will be treated with mandibular setback either mono or bimaxilary surgeries Patient with facial deformity will be treated with mandibular setback either surgery first approach or orthofirst approach. Sufficient dentition to reproduce the occlusal relationships Patient's consent to participate Exclusion criteria: Patients with any systemic disease that may affect normal healing Intra-bony lesions or infections that may interfere with surgery. Previous orthognathic surgeries. Patients with all types of facial clefts

Active Comparator
mandibular setback using low medial cut ostetomy
mandibular setback using high medial cut ostetomy
mandibular setback using low medial cut ostetomy by keeping the cut ''low'' or close to the mandibular occlusal plane and ''short'' or terminating anterior to the lingula.
mandibular setback by placement of the medial ramus osteotomy cut 'high', just a few millimeters above the lingula, superior and lateral to the entrance point of the inferior alveolar nerve (IAN) into the mandibular foramen ,
