Orthognathic Surgeries and Pharyngeal Airway Space

Not Applicable

Completed

• Conditions: Mandibular Prognathism

• Registration Number: NCT04629859
• Lead Sponsor: Fayoum University

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

Primary Outcome Measures

Name	Time	Method
total pharyngeal airway space surface area	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 Outcome Measures

Name	Time	Method
Epworth sleepiness scale	6 months	(0-24) score to assess sleep apnea indirect
