Quantification of Vocal Tract Configuration of Older Children with Down syndrome: A Pilot Study
Acoustic Pharyngometer
The Eccovision® Acoustic Pharyngometer allows users to quickly and easily measure a patients pharyngeal airway size and stability from the Oral Pharyngeal Junction to the Glottis. The Pharyngometer graphically displays the relationship between the cross-sectional area of the airway and distance down the airway in centimeters. Studies have shown a clear relationship between the existence of OSA and a narrow, collapsible, airway. The Pharyngometer accomplishes these measurements using acoustic reflection technology, similar to a ships sonar. Sound waves are projected down the airway and reflected back out in such a way that the Pharyngometer software can analyze and quantify changes in the airways cross-sectional area. The test is minimally invasive and takes 2-5 minutes to complete.
