OBJECTIVES/HYPOTHESIS: The aim of the study was to introduce and study the role of standardized views for ultrasound of the major salivary glands in resident learning and retention.
Methods description and prospective case series.
Five otolaryngology residents and two patient models were recruited for this study. The participants were timed on their identification of the submandibular gland, sublingual gland, and parotid gland and associated key anatomic structures. Participants were then timed again immediately after being presented a standardized view for each salivary gland: the longitudinal submandibular gland, transverse parotid gland, and submental transverse views. The same participants were then timed one month later to determine retention. A Wilcoxon signed-rank test was used to evaluate whether time to identification was equal pre- and post-standardized view instruction.
There was a significant improvement from pre- to post-standardized view instruction in all glands, which was sustained one month later. Practically speaking, assessment times for all participants at the one-month measurement were reasonable, with averages of 71, 42, and 114 s for the submandibular gland, sublingual gland, and parotid gland respectively.
Standardized views provided otolaryngology ultrasonography learners with a reliable, fast, and memorable way to assess the salivary glands and their related structures.
目的/假设：本研究旨在介绍并研究标准化的主要唾液腺超声视图在住院医师学习和保留中的作用。
方法描述和前瞻性病例系列。
本研究招募了 5 名耳鼻喉科住院医师和 2 名患者模型。参与者需要在规定时间内识别下颌下腺、舌下腺和腮腺及其相关关键解剖结构。然后，参与者在观看每个唾液腺的标准化视图后再次计时：下颌下腺的纵向视图、腮腺的横向视图和颏下横向视图。同样的参与者在一个月后再次计时以确定保留情况。使用 Wilcoxon 符号秩检验评估在接受标准化视图指导前后识别时间是否相等。
在所有腺体中，从标准化视图指导前到指导后，识别时间都有显著改善，一个月后仍能保持。实际上，所有参与者在一个月测量时的评估时间都合理，下颌下腺、舌下腺和腮腺的平均时间分别为 71、42 和 114 秒。
标准化视图为耳鼻喉科超声学习者提供了一种可靠、快速和易于记忆的评估唾液腺及其相关结构的方法。
