ABSTRACT
Objective:
To study the anatomical correlation between dental arch and the volume of upper airway in patients with obstruc-tive sleep apnea hypoventilation syndrome(OSAHS).Methods:
Dental arch architecture and upper airway volume were measured by cone beam CT(CBCT) in the subjects with OSAHS(n=22) and without OSAHS(n=19). The correlation between dental arch and the supper airway volume in OSAHS patients was analyzed.Results:
The length of the upper dental arch and the height of palate in OSAHS patients were larger than those of the controls(All, P<0. 05). Cross-sectional area of nasopharynx and retropalatal and the total volume of upper airway were negatively correlated with the palatal height and upper dental arch length(P<0. 05), while positively correlated with upper dental arch of molar regions(P<0. 05).Conclusion:
The abnormal shape of upper dental arch is related to the airway vol-ume of nasopharynx and retropalatal region in patients with OSAHS.
