To investigate hyoid bone position and airway volume in subjects with adenoid hypertrophy, tonsillar hypertrophy, and adenotonsillar hypertrophy compared to subjects with nonobstructive adenoids or tonsils and to assess the correlation between hyoid bone and airway parameters.
A total of 121 subjects were grouped based on adenoid or tonsillar hypertrophy into four groups, as follows: (1) control group (C-group), (2) adenoid hypertrophy group (AH-group), (3) adenotonsillar hypertrophy group (ATH-group), and (4) tonsillar hypertrophy group (TH-group). Hyoid bone position and airway volumes were measured. The Kruskal-Wallis test was used for intergroup comparison, followed by pairwise comparison using the Mann-Whitney U-test. Bivariate correlation was conducted using Spearman correlation coefficients. Multiple linear regression was performed to create a model for airway volume based on hyoid bone predictive variables.
No significant difference was found between subjects with isolated adenoid or tonsillar hypertrophy compared to the C-group. However, the ATH-group exhibited a significantly decreased hyoid bone vertical distance (HV), total airway volume (TA volume), and retroglossal airway volume (RG volume) compared to the C-group. HV and age had a high potential in terms of explaining the RG volume, whereas the TA volume and retropalatal airway volume (RP volume) models were not as successful as the RG volume counterpart.
Subjects in ATH-group were characterized by an elevated hyoid bone position and constricted TA volume and RG volume compared to those in the C-group. HV and age were predictor variables that best explained retroglossal airway volume.
比较腺样体肥大、扁桃体肥大和腺样体扁桃体肥大患者与非阻塞性腺样体或扁桃体患者的舌骨位置和气道容积，探讨舌骨与气道参数的相关性。
根据腺样体或扁桃体肥大情况，将 121 例患者分为 4 组：（1）对照组（C 组），（2）腺样体肥大组（AH 组），（3）腺样体扁桃体肥大组（ATH 组）和（4）扁桃体肥大组（TH 组）。测量舌骨位置和气道容积。采用 Kruskal-Wallis 检验进行组间比较，然后采用 Mann-Whitney U 检验进行两两比较。采用 Spearman 相关系数进行双变量相关分析。采用多元线性回归建立基于舌骨预测变量的气道容积模型。
与 C 组相比，单纯腺样体或扁桃体肥大患者之间无显著差异。然而，ATH 组与 C 组相比，其舌骨垂直距离（HV）、总气道容积（TA 容积）和会厌后气道容积（RG 容积）显著降低。HV 和年龄在解释 RG 容积方面具有很高的潜力，而 TA 容积和腭后气道容积（RP 容积）模型不如 RG 容积模型成功。
ATH 组患者的舌骨位置升高，TA 容积和 RG 容积较 C 组狭窄。HV 和年龄是解释会厌后气道容积的最佳预测变量。
