Our practice uses the Eccovision Acoustic Pharyngometer / Rhinometer system from Sleep Group Solutions to test our patients nasal and oral airways. The device sends sound waves into the airway and the reflected sound waves are measured by the machine to tell us how big the airway is. The Rhinometer measures the nasal airway and the Pharyngometer measures the oral airway. Both systems are FDA cleared and a highly effective way for us to identify the site and severity of airway collapse as it related to snoring and sleep related breathing problems.
