Abstract: Objective To conduct a three-dimensional comparative study on upper airway symmetry between patients with non-syndromic cleft lip and palate and populations with skeletal Class Ⅰ. Methods Fifty-one cases of non-syndromic cleft lip and palate patients (37 males, 14 females, average age (17.40±5.93) years) and 53 cases of skeletal Class Ⅰ populations (39 males, 14 females, average age (17.40±6.07) years) were included. Cone-beam CT was taken, and Dolphin 3D 11.9 software was used for three-dimensional measurement and analysis. SPSS 25.0 software package was used for independent sample t-test to conduct the analysis of upper airway symmetry. Results The nasopharyngeal and velopharyngeal segments of the upper airway in patients with unilateral cleft lip and palate were asymmetrical structures (P<0.05), and the cross-sectional diameter of the affected side was smaller than that of the healthy side; while the patients with bilateral cleft lip and palate and skeletal Class Ⅰ populations had an asymmetric structure (P<0.05). The nasopharyngeal and velopharyngeal segments of the upper airway were basically symmetrical (P<0.05). Conclusion In the cross-sectional diameter of the upper airway in patients with unilateral cleft lip and palate, the affected side tends to be biased toward the healthy side, and attention should be paid to the ventilation and respiration of the affected side of cleft lip and palate.
