- 语音外科手术 语音外科手术
- 生物工程是生物工程.
- 声学 声学 在声学方面
背景情况:
- 单侧声麻往往需要手术干预,如I型胸膜整形 (TT1).
- 在TT1中优化植入物放置对于有效的语音恢复至关重要.
研究的目的:
- 为了研究TT1中下部植入物放置对语音产生的影响.
- 通过使用数值模拟,分析植入物参数如何影响声动态和声学结果.
主要方法:
- 从狗CT扫描中重建了喉和植入物几何形状.

Larynx
5.4K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
697
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...
