Abstract
Objective: The objective was to study the effect of orthodontic therapy regarding the position of the hyoid bone and upper airways in nighty-one 6-21 year-old Caucasian patients with normoclussion.
Methods: Nineteen variables were analyzed by teleradiography. The differences were analyzed with the ANOVA test of repeated measures with an intra-group factor for two occasions.
Results: The statistical analysis revealed a greater influence on the variables Hy-MP (12.3 vs 14.2), Hps-C3 (25.2 vs 28.1), Hpi-C3 (28.8 vs 35.5), H°-C3 (14.4 vs 12.7), Hps-Rg (36.0 vs 42.7), Hpi-Rg (34.1 vs 39.7), USP (16.2 vs 20.2), MPP (12.9 vs 14.8), C3P (10.6 vs 12.8), PNS-Ba (43.5 vs 66.5), PtV-Ad (12.0 vs 17.1) and PtM-Ba (33.9 vs 35.9), and Ad2-SO (24.16 vs 20.87).
Discussion: Significant differences were observed between most of the airway and hyoid bone variables before and after orthodontic treatment in our Spanish pediatric population, especially in the nasopharynx.
目的目的是研究正畸治疗对 6 至 21 岁白种人正常腭裂患者舌骨和上呼吸道位置的影响：方法：通过远程放射成像对 19 个变量进行分析。方法：通过远程放射成像对 19 个变量进行分析，采用重复测量的方差分析检验对两个场合的组内因子进行差异分析：统计分析显示，Hy-MP（12.3 vs 14.2）、Hps-C3（25.2 vs 28.1）、Hpi-C3（28.8 vs 35.5）、H°-C3（14.4 vs 12.7）、Hps-Rg（36.0 vs 42.7）、Hpi-Rg（34.1 vs 39.7）、USP（16.2 vs 20.2）、MPP（12.9 vs 14.8）、C3P（10.6 vs 12.8）、PNS-Ba（43.5 vs 66.5）、PtV-Ad（12.0 vs 17.1）和 PtM-Ba（33.9 vs 35.9）以及 Ad2-SO（24.16 vs 20.87）：在我们的西班牙儿童群体中，正畸治疗前后大部分气道和舌骨变量之间都存在显著差异，尤其是鼻咽部。
