概括
确定胎儿 tympanic环前后直径 (TRAPD) 的参考帮助在产前查外部听力介质 (EAM) 异常. 这些新的参考和形态学为EAM条件提供了可靠的诊断值.
科学领域:
- 产前成像 产前成像
- 胎儿的发育 胎儿的发育
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
背景情况:
- 准确的产前诊断外部听力系统 (EAM) 异常是具有挑战性的.
- 确定胎儿结构的规范性数据对于识别偏差至关重要.
研究的目的:
- 为了创建胎儿耳环前后直径 (TRAPD) 的参考范围,从怀孕12周到31周+6周.
- 评估TRAPD和胎儿生长参数之间的相关性.
- 评估TRAPD在检测EAM异常方面的诊断性能.
主要方法:
- 追溯分析了722个胎儿超声波 (704个正常,18个异常).
- 测量TRAPD使用横向的横头平面成像.
- 根据妊娠年龄分层的TRAPD参考文献的开发和对应性分析,包括双直径,头周,耳朵长度和耳朵宽度.
主要成果:
- 随着妊娠年龄的增长,TRAPD表现出非线性增长,稳定在30+5周左右.
- 在TRAPD和妊娠年龄 (r=0.914),双双耳直径 (r=0.893),耳朵长度 (r=0.904) 和耳朵宽度 (r=0.914) 之间观察到强烈的相关性.
- 结合TRAPD,耳朵长度和耳朵宽度的预测模型在识别EAM异常时实现了99.78%的准确性;TRAPD平均值<5.6毫米显示在怀孕22周后对EAM异常具有100%的灵敏度和99.8%的特异性.
结论:
- 已建立的TRAPD参考文献和形态评估提供了一个可靠的方法,用于EAM异常的产前查.
- 从TRAPD测量中得出的可操作的临床值可以帮助早期检测EAM条件.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

1.1K
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...
