The Eccovision device uses acoustic reflection technology to accurately map out the size, structure and collapsibility of the oral and nasal airway. The Eccovision is widely used in ENT, Orthodontic and Sleep Disorders Dentistry practices.
Orthodontists can use the device to examine the health of the airway before, during and after treatment. It is well documented that a compromised nasal airway is a cause of mouth breathing which is a primary cause behind facial growth and orthodontic problems. It is critical to have accurate airway records and ability to recognize these obstructions.
Sleep Disorders Dentists use the Pharyngometer to screen patients prior to diagnosis. A narrow airway reading on the Pharyngometer correlates to higher Apnea Hypopnea Indices once the person is diagnosed. After diagnosis the pharyngometer helps to show us how the airway changes in repsonse to mandibular advancement. It has been concluded that the pharyngometer was accurate in ruling out patients who would not benefit from oral appliances 95% of the time.
Data from Pharyngometer & Rhinometer tests is displayed on an easy-to-read graph.
Acoustic Pharyngometry Measurement of Minimal Cross-Sectional Airway Area Is a Significant Independent Predictor of Moderate-To-Severe Obstructive Sleep Apnea
