Comparative Evaluation of the Pharyngeal Airways and Related Soft Tissues of Unilateral and Bilateral Cleft Lip and Palate Patients With the Noncleft Individuals
2017
Aim: This study is a comparison of pharyngeal airways and associated soft tissues of unilateral and bilateral cleft lip and palate patients with the noncleft individuals. Materials and Methods: Twenty-four unilateral cleft lip and palate patients (UCLP), 21 bilateral cleft lip and palate patients (BCLP), and 26 noncleft patients (NC) between ages 15 to 17 were included in the study. Eleven linear, 1 angular, and 1 proportional measurements were carried out on pretreatment lateral cephalometric head films of these individuals. Results: The nasopharyngeal depths were markedly reduced in BCLP when compared with the NC (P < .001) and UCLP (P < .01) with a significant difference (P < .01) also among UCLP and NC. Minimum space behind the tongue concerning BCLP and UCLP were significantly lower compared to the NC (P < .001 and P < .01, respectively). In pairwise comparison among the clefts, BCLP showed significant (P < .05) narrowing of this distance. Tongue heights and velar lengths were significantly (P < ....
