概括
顺序耳植入器 (CI) 可以在一半以上的患者中保持听力,改善语音理解. 然而,在第二种植入的耳朵中,听力保护不那么成功,植入时的年龄是关键因素.
科学领域:
- 听力学 听力学是指听力学.
- 神经外科 神经外科
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
背景情况:
- 双边耳植入器 (CI) 与单边CI相比具有优势,特别是在噪音和声音定位中的语音理解方面.
- 在CI后的声学听力保护对于最佳结果至关重要,但影响它的因素仍然不太清楚.
- 顺序性CI患者提供了一个独特的模型来研究听力保护,因为固有的个人控制.
研究的目的:
- 为了研究听力保护率和影响因素在患者进行顺序耳植入.
- 评估顺序IC对语音感知和声学听觉随着时间的推移的影响.
- 确定第二种植入耳朵的听力损失背后的潜在机制.
主要方法:
- 对从23名残留听力患者获得的前性收集数据的回顾性分析.
- 听力测量数据 (纯音调平均值,PTA) 在手术前和后收集.
- 使用CNC和AzBio材料进行语音感知评估. 植入前和后.
主要成果:
- 56.5%的患者实现了双边听力保护;81%的初始听力保护患者在第二种植入物后保持了它.
- 语音理解得分在顺序后CI显著改善 (p=0.019).
- 在第二种植入的耳朵 (p=0.014) 中观察到听力保护的显著下降,植入时的年龄与听力损失相关 (p=0.040).
结论:
- 序列IC可以改善语音理解,同时在很大一部分患者中保持听力.
- 在第二种植入的耳朵中,听力保护不那么成功,这表明潜在的免疫媒介炎症过程.
- 植入时的年龄是影响顺序性CI后长期听力保护的关键因素,需要进一步研究炎症机制.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

3.4K
In statistics, correlation describes the degree of association between two variables. In the subfield of linear regression, correlation is mathematically expressed by the correlation coefficient, which describes the strength and direction of the relationship between two variables. The coefficient is symbolically represented by 'r' and ranges from -1 to +1. A positive value indicates a positive correlation where the two variables move in the same direction. A negative value suggests a...

The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable x and the dependent variable y.
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the...
