Eccovision Acoustic Pharyngometry

Eccovision® Acoustic Diagnostic Imaging Acoustic Pharyngometer™ is a diagnostic system used for the objective assessment of the upper respiratory airway.  Eccovision utilizes a patented, state of the art acoustic signal processing technology to provide graphical representations of airway patency as a function of distance from the airway opening.

Eccovision® Acoustic Pharyngometry® is a dynamic test that determines dimension of the oral airway past the glottis while the patient is breathing.  Computer processing of the incident and reflected sound signals provides an area-distance curve representing the lumen together with minimal cross- sectional area and volume.  The technique is minimally invasive, results are precise and reproducible and can be obtained rapidly and repeatedly.

Clinical & physiological applications include: 

• Demonstration of structural and functional abnormalities of the pharynx and glottis
• Airway response to therapeutic intervention
  Site of airway obstruction
• Effect of Mandibular Advancement on the hypopharynx
  Graphically displays changes in the oral airway with lower jaw advancement
• Patients and dentists can see the effect an oral appliance has on airway size
• Allows dentists to view the airway for treatment and referal
