- 空气动力学 航空动力学
- 面外科手术 面外科手术
背景情况:
- 裂口 palates 显著影响话语和吞,由于喉功能不充分.
- 手术正 (palatoplasty) 的目的是恢复功能,但结果各不相同.
- 了解空气流动力学对于优化手术技术至关重要.
研究的目的:
- 通过计算流体动力学 (CFD) 来研究喉气流压力和口腔整形后的速度变化.
- 为了比较不同软 palates 长度 (延伸) 和高度 (升高) 对 velopharyngeal 关闭的影响.
- 评估CFD作为虚拟外科设计和结果预测的工具.
主要方法:

Suctioning the Nasopharyngeal Airway
221
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Pharynx
1.0K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
