[The application of cineMRI in evaluation of upper airway obstruction levels in complicated pediatric OSAS].

ABSTRACT

Objective:The aim of this study is to explore the role of cineMRI in the localization of upper airway obstruction in complicated pediatric OSAS. Method:Eleven persistent OSAS and 11 complex OSAS patients underwent cineMRI. Each patient was imaged midline sagittal and axial magnetic resonance cine image. The obtained sagittal and axial images were displayed in cine format, creating a real time "movie" of airway motion, to make a personalized treatment for each child. Polysomnography was performed to evaluate the effectiveness of cineMRI directed treatment for pediatric OSAS. Result:cineMRI could effectively define the upper airway obstruction level. There was a significant improvement in AHI (P=0.019) and saturation nadir (P<0.01). Conclusion:cineMRI is an effective method for assessing the level of airway obstruction on persistent or complex pediatric OSAS.
