This study looks at how jaw surgery called maxillomandibular advancement with counterclockwise rotation affects breathing during sleep in people with moderate to severe obstructive sleep apnea who cannot tolerate standard treatments such as Continous Positive Airway pressure treatment. The participants are followed over time to see whether the surgery improves sleep apnea symptoms, daytime sleepiness, and airway size, and whether these improvements last. Advanced three-dimensional imaging and airflow analysis are used to better understand how the surgery changes the airway and breathing. The goal is to evaluate the long-term effectiveness and safety of this surgical treatment.
