Abstract:
Objective:To analyze the characteristics and differences of upper airway forms in the adults with class Ⅱ sagittal facial type of different vertical facial types and investigate the correlation between craniofacial structures and upper airway forms.Methods:Cephalograms of 135 adults with classⅡsagittal facial type of different vertical facial types were collected.60 cases were males and 75 cases were females.All the cephalograms were measured in sagittal upper airway depths.The differences were compared between genders,and also among different vertical facial type groups.Results:Among different vertical facial type groups,only the sagittal depths of nasopharynx(PNS-Ba、PNS-R)of the males and PNS-Ba of the females in high angle groups were smaller than that in average and low angle groups(P0.05),but the values of V-LPW of the males were larger than that of the famales in all vertical facial type groups(P
