概括
快速大扩张 (RME) 改善上呼吸道 (UA) 气流,特别是在年轻的患者中. 中期改善与自然的面发育和减少的腺质组织有关.
科学领域:
- 矯正牙科 矯正牙科是一種矯正牙科.
- 头骨面部的发展
- 气道生理学 气道生理学
背景情况:
- 已知快速上扩张 (RME) 可降低鼻腔空气流阻力.
- RME对上呼吸道 (UA) 空气流特征的中期影响不太清楚,特别是考虑到正常的面发育.
研究的目的:
- 使用计算机流体动力学 (CFD) 评估RME后UA气流 (压力和速度) 中期变化.
- 为了比较两个不同的基于年龄的群体中的这些变化:早期 (6-9岁) 和晚期 (11-14岁) 的扩张群体.
主要方法:
- 48名受试者的回顾性队列研究 (25名早期,23名晚期扩张).
- 从基线 (T0) 和RME后12个月 (T1) 的CBCT扫描细分出鼻和喉解剖学.
- 用于分析UA空气流变量 (压力,速度) 和解剖测量的CFD模拟.
主要成果:
- 基线气流压力和速度在早期扩张组中较高.
- 在T1时,UA空气流参数在两个组中均显著改善,在早期扩张组中改善更大.
- 空气流变化与后部横截面积 (CS2) 和鼻 (NP) 大小负相关,可能是由于腺组织减少.
结论:
- 正常的面发育变化和自发的腺组织回归是影响RME后12个月UA气流的关键因素.
- 研究结果表明,RME可能会对UA空气流产生积极影响,在年轻人中影响更为明显.
- 结果仅限于没有阻塞性腺膜缩症的回顾性正义牙科样本.

Factors Affecting Pulmonary Ventilation
914
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Anatomy of Respiratory System I: Upper Respiratory Tract
694
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....
