ABSTRACT
Objective:
To study the relationship among upper airway volume of naso-pharyngeal, yelo-pharyngeal,glosso-pharyngeal, hypo-pharyngeal area which measured by spiral computed tomography three-dimensional reconstruction technique, apnea hypopnea indexes, and the lowest oxygen saturation in patients with OSAHS.Method:
â fifty-one patients with OSAHS were received polysomnography, and then were divided into groups by the AHI,LSaO2 values. â¡To measure upper airway volume at normal breath and Müller maneuver state using spiral computed tomography three-dimensional reconstruction technique of CT measurement, and to calculate volume change rate and observe the upper airway compliance. â¢To analyses the relationship between upper airway volume and AHI,LSaO2 values.Result:
The smallest upper airway volume of OSAHS was at the velo-pharyngeal level; the volume of velo-pharyngeal level were negatively correlated with AHI during normal respiration and Müller's maneuver state and were positively correlated with LSaO2; the volume of hypo-pharyngeal were negatively correlated with AHI during normal respiration; the volume of glosso-pharyngeal were positively correlated with LSaO2 during Müller's maneuver state.Conclusion:
â The volume of velo-pharyngeal level with OSAHS patients can reflect the severity of AHI,LSaO2. â¡The measurement of upper airway volume using spiral computed tomography three-dimensional reconstruction technique is good method to evaluate the upper airway compliance of OSAHS patients.
