Objective To study the difference of upper airway form in children and adults with normal sagittal and vertical skeletal types. Methods Cephalograms of 120 children and adults with normal sagittal and vertical skeletal types were retrospectively investigated by computerized cephalometric analysis. The sagittal depths of upper airway were measured, and the differences were compared between male and female, and between children and adults. Results There was no gender difference of the sagittal depth of upper airway in children and adults except the V-LPW in adult. The PNS-R, PNS-AD2 and V-LPW of upper airway in male increased from mixed dentition, early permanent dentition to permanent dentition, but the SPP-SPPW, U-MPW, TB-TPPW had no significant changes. The PNS-UPW increased from mixed dentition to early permanent dentition and had no significant change from early permanent dentition to permanent dentition. In female, the PNS-R, PNS-AD2 increased from mixed dentition, early permanent dentition to permanent dentition, but the SPP-SPPW, U-MPW did not show significant changes. The PNS-UPW, TB-TPPW, V-LPW increased from mixed dentition to early permanent dentition and had no obvious changes from early permanent dentition to permanent dentition. Conclusion The upper airway form in children and adults is different, and the normal values of upper airway by age should be established.
