Effect of Differing Mandible and Maxilla Osteotomies Manipulation on Velar, Oropharyngeal, and Hypopharyngeal Diameter

Maxillomandibular advancement is an effective surgical treatment for medically refractory moderate to severe obstructive sleep apnea. Different degrees and vectors of bony advancements increase upper airway dimensions as a result of their soft tissue attachments. Previous studies have analyzed clinical efficacy by demonstrating increased airway dimension on pre and post-operative imaging, sleep study results, and drug induced sleep endoscopy (DISE). These studies are limited to analyzing the effects of single movements.
