    Assessment of pharyngeal airway volume in adolescent patients affected by bilateral cleft lip and palate using cone beam computed tomography
    (E H ANGLE EDUCATION RESEARCH FOUNDATION, INC, 2014) Celikoglu, Mevlut; Ucar, Faruk I.; Sekerci, Ahmet E.; Buyuk, Suleyman K.; Ersoz, Mustafa; Sisman, Yildiray
    Objective: To test the null hypothesis that there were no significant differences for pharyngeal airway volumes between the adolescent patients affected by bilateral cleft lip and palate (BCLP) and well-matched controls using cone beam computed tomography. Materials and Methods: The study sample consisted of 16 patients (11 female and 5 male; mean [SD] age 14.1 [2.1] years) affected by BCLP and 16 patients (10 female and 6 male; mean [SD] age 13.4 [2.0] years) as age- and sex-matched control group. Craniofacial measurements and pharyngeal airway dimension, area, and volume measurements of patients in both groups were calculated and statistically examined using Student's t-test and multiple linear regression analyses. Results: Statistically significant differences were found between the BCLP and control groups for SNB (P <.05), SN-GoGn (P <.05), Co-A (P <.05), PAS (P <.01), minAx (P <.01), and oropharyngeal airway volume (P <.05). The most predictive variables for oropharyngeal airway volume were found as PAS (r =.655 and P =.000) and minAx (r =.787 and P =.000). Conclusions: The null hypothesis was rejected. Oropharyngeal (P <.05) and total (P>.05) airway volumes were found to be less in the BCLP group, and thus the treatment choice in these patients should have positive effects on the pharyngeal airway.

    Effects of cleft lip and palate on the development of permanent upper central incisors: a cone-beam computed tomography study
    (OXFORD UNIV PRESS, 2015) Celebi, Ahmet A.; Ucar, Faruk I.; Sekerci, Ahmet E.; Caglaroglu, Murat; Tan, Enes
    Objective: The aim of this study was to evaluate 1. the differences among the cleft sides of unilateral cleft lip and palate (UCLP) patients, non-cleft sides of the same UCLP patients and well matched control patients in the root development and position of permanent upper central incisors and 2. possible gender differences. Materials and methods: The study sample consisted of 40 patient (20 males and 20 females; mean age: 14.84 +/- 3.2 years) with non-syndromic UCLP patients, and 40 control patients (20 males and 20 females; mean age: 13.38 +/- 1.6 years). Cone-beam computed tomography (CBCT) images were taken off from all patients. All tomographs were obtained in supine position by using CBCT (NewTom 5G, QR, Verona, Italy). Results: Significant smaller root volume of central incisor was observed on the cleft side than on the non-cleft side of UCLP patients (P < 0.05). No significant difference in the root development and position of the central incisors was found between the non-cleft side of the UCLP and the control group (P > 0.05). There were no statistically significant gender differences in any linear, angular, or volumetric measurements (P > 0.05). Only the root volume of the cleft side was smaller in females than in males (P < 0.05). Conclusions: In general, root volumes of central incisors on the cleft side were 12.15 per cent smaller than non-cleft side. Root development of the central incisor was much more influenced by the cleft in females than in males.
