This study aimed to compare nasopharyngeal airway volume in cleft lip and palate patients with normal individuals using Cone Beam Computed Tomography (CBCT). In this cross-sectional study, 40 CBCT scans of 9 to 12-years-old patients were enrolled and divided into 3 groups: normal individuals (n=16), unilateral cleft lip and palate (UCLP, n=14) and bilateral cleft lip and palate patients (BCLP, n=10). Superior and middle pharyngeal airway volumes and nasal width were measured and compared between 3 groups. ANOVA and χ 2 tests were used for statistical comparison. P <0.05 was considered significant. Superior airway volume was not significantly different between the 3 groups ( P =0.36). However, there was a significant difference between the 3 groups regarding middle pharyngeal volume ( P =0.49) and nasal width ( P =0.021). There was not a significant difference in the upper and middle pharyngeal volume and also nasal width between the 2 sexes. Considering different dimensions of evaluation of the pharyngeal airway volume of cleft lip and palate patients, the evaluation of airway volume is essential during orthodontic or orthognathic surgical treatments that expand or protect the maxilla.
本研究旨在使用锥形束 CT（CBCT）比较唇腭裂患者与正常个体的鼻咽气道容积。在这项横断面研究中，共纳入了 40 名 9 至 12 岁患者的 CBCT 扫描，并将其分为 3 组：正常个体（n=16）、单侧唇腭裂（UCLP，n=14）和双侧唇腭裂患者（BCLP，n=10）。测量并比较了 3 组患者的鼻咽上部和中部气道容积以及鼻宽。采用 ANOVA 和 χ 2 检验进行统计学比较。P<0.05 被认为具有统计学意义。3 组之间的上气道容积无显著差异（P=0.36）。然而，中咽气道容积（P=0.49）和鼻宽（P=0.021）存在显著差异。2 性别的上、中咽气道容积和鼻宽也无显著差异。考虑到唇腭裂患者的咽气道容积评估的不同维度，在正畸或正颌手术治疗中扩大或保护上颌骨时，气道容积的评估至关重要。
