Nasopharyngeal Airway Volume for Different GOSLON Scores in Patients With Unilateral Cleft Lip and Palate
2015
Objective: The aim of this study is to evaluate the nasopharyngeal airway volumes of patients with unilateral cleft lip and palate (UCLP) with different GOSLON scores. Methods: The study sample consisted of 34 patients with UCLP and 20 controls with no cleft history. In the UCLP group, three experienced examiners used the GOSLON Yardstick to rate dental arch relationships, and the sample was divided into three groups as GOSLON 2 (G2) (n = 13), GOSLON 3 (G3) (n = 10), and GOSLON 4 (G4) (n = 11). Airway volumes were constructed using three-dimensional computed tomography data and divided into four compartments named the nasal airway, and superior, middle, and inferior pharyngeal airways. Results: No statistically significant difference was detected among G2, G3, and G4 between the constitutive airway departments of the nasopharyngeal region. However, nasal airway volumes were significantly higher in the control group when compared with the UCLP group. Discussion: Although there was no correlation among the ...
