摘要
目的通过比较不同时期唇腭裂术后患者上气道形态,分析唇腭裂术后患者上气道形态发育趋势。方法选取单侧完全性唇腭裂术后儿童及成年患者各30例,分别进行上气道三维重建并进行分区测量,采用独立样本t检验比较两组间各测量指标的差别。结果与儿童组(UCLP-1)相比,成年组(UCLP-2)气道各段横截面积及正中矢状径均有增大的趋势,除S1min(P=0.089)、S2min(P=0.058)、S3min(P=0.081)外,差异均具有统计学意义(P〈0.05),舌咽段与喉咽段气道冠状径均有增大的趋势,差异具有统计学意义(P〈0.05)。结论随年龄增长,单侧完全性唇腭裂术后患者上气道各段的横截面积、正中矢状径和舌咽段、喉咽段冠状径逐渐增大;鼻咽部和腭咽部的冠状径没有发生具有统计学意义的变化,提示唇腭裂患者在腭平面处气道冠状向宽度发育受限。
Objective To analyze the growth of upper-airway in patients with unilateral cleft lip and palate. Methods Thirty adult and 30 adolescent patients with operated unilateral cleft lip and palate were included in the study. Three-dimensional evaluation of the upper-airway was carried out using cone beam CT (CBCT). Statistical analysis was performed. Results Compared with adolescent patients, the cross section area and the central sagittal diameters of the upper-airway in adult patients showed an increasing tendency. The coronal diameter of glossopharyngeum and laryngopharynx showed the same tendency (P〈0. 05). Conclusions Most of the measurements which reflect the dimension of upper-airway in patients with cleft lip and palate increased with age. However, the coronal diameter in the nasopharynx and palatopharynx remained unchanged.
