Tracheal wall motion was monitored and sonographic measurements of the airway lumen were obtained during quiet respiration, deep respiration, and the M\u00fcller maneuver. Tracheal displacement during the M\u00fcller maneuver was monitored and quantified. Measurements were compared between groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Adequate visualization of cervical tracheal dimensional changes during the M\u00fcller maneuver was obtained in 91.15% of patients with OSAHS and 99.12% of healthy subjects. The cervical trachea had the smallest lateral diameter during the M\u00fcller maneuver (<jats:italic>P<\/jats:italic> &amp;lt; 0.001) in patients with OSAHS and healthy controls. The cervical trachea moved caudally during the M\u00fcller maneuver, and its peak tracheal displacement was greater in patients with OSAHS than that in the healthy controls (<jats:italic>P<\/jats:italic> &amp;lt; 0.001). There was a positive relationship between peak tracheal displacement during the M\u00fcller maneuver and apnoea-hypopnoea index (AHI; <jats:italic>P<\/jats:italic> &amp;lt; 0.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>OSAHS patients have greater caudal tracheal displacement and greater tracheal size than healthy controls.
