Acoustic Pharyngometry is a non-invasive diagnostic technique that uses acoustic reflection to measure the size and stability of your airway. With this data, we generate a detailed airway cross-sectional graph, which helps us pinpoint any airway narrowing or obstruction that may be affecting your sleep and breathing.

The best part? It’s completely pain-free, takes only a few minutes, and delivers highly accurate, reproducible results—no radiation or imaging required.

During the test, you’ll sit upright and gently bite down on a mouthpiece similar to a snorkel. As you breathe naturally, the pharyngometer sends sound waves down your airway. These waves bounce back and are analyzed to identify:

• The most unstable areas of your airway
  
• Regions that may collapse during sleep
  
• The optimal jaw position for treatment using an oral appliance
  

We then introduce a bite guide to simulate how an oral appliance would affect your airway. This lets us find the best starting point for treatment and ensures the appliance is tailored to your unique needs.

Many dentists fit oral appliances based on approximations—but not us. Acoustic pharyngometry gives us a scientific, three-dimensional view of your airway, which means we can:

• Maximize airway opening for better airflow
  
• Personalize your oral appliance for comfort and effectiveness
  
• Provide results that rival CPAP in select cases
  
• Reduce the risk of improper appliance fit
