To develop a novel ultrasound (US) plane to diagnose palatine tonsillar hypertrophy objectively in children.
Tonsillar ultrasonography of children (age 2-14 years) who had a clinical diagnosis of tonsillar hypertrophy or not were analyzed retrospectively. Clinical data (including gender, age, body mass index (BMI)), and volume (V) of tonsils measured by the US, were recorded. Furthermore, we found a new US plane to diagnose tonsillar hypertrophy and named it the submental oblique cross-section. In this plane, diameters of the left tonsil, right tonsil, and central oropharynx were designated as T1, T2, and O. Then, we calculated the ratio by the formula (T1 + T2)/O.
A total of 172 cases (85 hypertrophy and 87 non-hypertrophy) were included in this study. There were no significant differences in gender (P = .844), age (P = .666), and BMI (P = .089) between the groups. In the non-hypertrophy group, the V of both sides had a positive linear correlation with age or BMI. In contrast, there was no linear correlation between ratio and age or BMI. The area under the curve (AUC) of ratio and V was 0.970 (95%CI: 0.947-0.993) and 0.835 (95%CI: 0.778-0.893) by receiver operating characteristic (ROC) analysis, respectively. The optimal cutoff value of ratio for diagnosis of tonsillar hypertrophy was 2.293 (sensitivity = 88.2%, specificity = 95.4%).
We established a new US section to evaluate tonsillar hypertrophy. This approach could be easily acquired and provide a reference value to guide clinical practice.
开发一种新的超声（US）平面，以客观诊断儿童的腭扁桃体肥大。
回顾性分析了经临床诊断为扁桃体肥大或非肥大的儿童的扁桃体超声检查。记录了临床数据（包括性别、年龄、体重指数（BMI））和 US 测量的扁桃体体积（V）。此外，我们发现了一种新的 US 平面来诊断扁桃体肥大，并将其命名为颏下斜切面。在此平面上，左扁桃体、右扁桃体和中央口咽部的直径分别指定为 T1、T2 和 O。然后，我们用公式（T1+T2）/O 计算比值。
本研究共纳入 172 例（85 例肥大和 87 例非肥大）。两组间的性别（P=0.844）、年龄（P=0.666）和 BMI（P=0.089）无显著差异。在非肥大组中，两侧的 V 与年龄或 BMI 呈正线性相关。相比之下，比值与年龄或 BMI 之间无线性关系。ROC 分析显示，比值和 V 的曲线下面积（AUC）分别为 0.970（95%CI：0.947-0.993）和 0.835（95%CI：0.778-0.893）。比值诊断扁桃体肥大的最佳截断值为 2.293（灵敏度为 88.2%，特异性为 95.4%）。
我们建立了一种新的 US 节段来评估扁桃体肥大。这种方法易于获得，并为指导临床实践提供了参考值。
