Abstract：Objective To analyze the correlation between OSAHS children's minimal width measured in cephalometrical film and the minimal cross section area in CBCT to determine the accuracy of airway 2D measurement in the diagnosis of airway obstruction.Methods 48 OSAHS children (10-12y) diagnosed by PSG were selected.All the subjects took cephalometrical film and CBCT at the same time.We got the airway volume and minimum cross section area by inputing DICOM form data into the dolphin.Make the Pearson correlation analysis concerning the minimum width and minimum cross section area.Results The minimal upper airway site measured in cephalometrical film was at the same place where the minimal cross section area lied.The mean value of the most narrow sagittal width was(3.79 ± 2.40)mm;the minimal cross section area measured in CBCT was (103.30 ± 34.47)mm2.Pearson correlation R =0.670 (P ＜ 0.05).Conclusion 2D and 3D upper airway measurement in OSAHS children has strong correction.Cephalometrical film can reflect the airway condition and can be used in the primary diagnosis of airway obstruction site and degree.
