A wide variety of pathologies can affect the palatine tonsils. Ultrasound is a commonly used modality for assessing head and neck masses in children; however, its use in tonsillar evaluation has not been widely explored. The objective of this study was to measure 3-dimensional tonsillar size with ultrasound, in centimeters, and correlate these measurements with actual ex vivo dimensions on pathology specimens.
We performed a prospective cohort study.
The study was set in a tertiary care children's hospital.
Children undergoing tonsillectomy were included in the study. Transcervical high-frequency ultrasonography (HFU) was performed prior to surgery to obtain 3-dimensional measurements of the right and left palatine tonsils. Mean sizes were compared to ex vivo tonsil measurements and correlations were obtained.
Seventy-five consecutive children underwent a transcervical HFU, with a total of 150 tonsils analyzed. The mean differences between HFU and pathology measurements were -0.08 cm and -0.24 cm for the right and left craniocaudal axes, -0.19 cm and -0.18 cm for the right and left mediolateral axes, and 0.05 cm and 0.03 cm for the right and left anteroposterior axes. Correlation coefficients between ultrasound and pathology measurements were all above 0.5.
HFU can accurately measure the size of pediatric tonsils in 3 dimensions.
多种病理学改变可影响腭扁桃体。超声是一种常用于评估儿童头颈部肿块的方法；然而，其在扁桃体评估中的应用尚未得到广泛探索。本研究的目的是用超声厘米测量扁桃体的 3 维大小，并将这些测量值与病理标本的实际离体尺寸进行相关性分析。
我们进行了一项前瞻性队列研究。
该研究在一家三级儿童保健医院进行。
本研究纳入了接受扁桃体切除术的儿童。在手术前进行经颈高频超声（HFU）以获得右、左腭扁桃体的 3 维测量值。将平均大小与离体扁桃体测量值进行比较并获得相关性。
75 例连续儿童进行了经颈 HFU，共分析了 150 个扁桃体。HFU 与病理测量之间的平均差异为右、左前后径为-0.08cm 和-0.24cm，右、左内外径为-0.19cm 和-0.18cm，右、左上下径为 0.05cm 和 0.03cm。超声与病理测量之间的相关系数均高于 0.5。
HFU 可以准确测量儿童扁桃体的 3 维大小。
