Overview
Brief Summary
twenty-four patients with dentoskeletal deformity of class III will be divided equally into two groups and will be subjected to orthognathic surgeries group A; will be treated by mandibular setback surgery while group B will be treated with bimaxillary orthognathic surgery in the form of mandibular setback and maxillary advancement surgeries. the total pharyngeal airway will be measured on lateral cephalometric radiographs, integrating retro-palatal and retro-glossal area, and statistically will be compared preoperative, immediate postoperative, and at 6 months post-surgically

Eligibility Criteria
Inclusion Criteria
- •dento-skeletal class III malocclusion which needed a surgical intervention with maxillary advancement surgery and/or mandibular set-back orthognathic surgery in the form of bilateral sagittal split osteotomy

Outcomes
Primary Outcomes
total pharyngeal airway space surface area
Time Frame: 6 months
Cephalometric analyses will be performed, the pharyngeal airway is demarcated inferiorly by a line passing through the tip of epiglottis and the superior tip of the hyoid bone, namely Line A, while the retro-glossal and the retro-palatal airway is separated by a line extending from the basion parallel to line A. All the reference points and lines were conveyed to the images . The Pharyngeal airway space was measured and compared.
Secondary Outcomes
- Epworth sleepiness scale(6 months)
