Tracking airway changes after jaw advancement surgery for sleep apnea

This is a registry study that follows patients who are receiving maxillomandibular advancement (MMA) surgery — a procedure that moves the jaw forward to permanently enlarge the airway and treat obstructive sleep apnea. Researchers will use 3D imaging scans to measure exactly how the airway changes after surgery, and will ask patients about improvements in daytime sleepiness and overall quality of life. The goal is to build a detailed database that helps doctors better plan this surgery and understand how well it works.

Obstructive sleep apnea is a serious condition where the airway collapses during sleep, causing breathing stops and poor sleep quality. While other treatments exist, jaw advancement surgery offers a permanent fix — but doctors want to better understand exactly how much the airway opens and whether improvements last over time.
