What percentage of OSA cases can be treated effectively with mandibular advancing devices?

10-25%
36-70%
50-80%
75-90%

The correct answer is: 36-70%

Mandibular advancing devices (MADs) are a common treatment option for obstructive sleep apnea (OSA). They work by repositioning the jaw forward to help keep the airway open during sleep. Research indicates that these devices can be effective for a substantial percentage of individuals with OSA, specifically in the range of 36% to 70%. This effectiveness can vary based on several factors, including the severity of OSA, patient anatomy, and compliance with device use. Treating OSA with MADs has been supported by many studies that have shown favorable outcomes in reducing apnea-hypopnea index scores and improving sleep quality. The range of 36-70% reflects a realistic expectation of success, indicating that while a significant portion of OSA cases can benefit from this treatment, it may not be suitable or effective for every patient. This statistic is important for practitioners when discussing treatment options with patients, ensuring a clear understanding of the potential outcomes associated with MADs.
