概括
甲状腺切除术可能会使语音质量恶化,主要是由于增加了声器不稳定性. 虽然在统计学上显著,但在甲状腺手术后的个体语音度量变化往往太小,无法在临床上具有相关性.
科学领域:
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 语音语言病理学 语音语言病理学
- 声学分析 声学分析
背景情况:
- 甲状腺切除术,即手术切除甲状腺,由于喉神经的接近,对声乐功能构成风险.
- 以前的研究集中在甲状腺切除术后的语音范围变化上,对语音质量的探索有限.
- 甲状腺手术后的语音质量变化可能是多方面的,并未完全理解.
研究的目的:
- 通过声学和电声学 (EGG) 测量,研究甲状腺切除术对语音质量的影响.
- 应用探索性方法来确定手术后各种语音指标的潜在变化.
- 为了将客观的语音测量与客观的患者投诉相关联.
主要方法:
- 对57名接受甲状腺手术的患者进行了回顾性语音映射分析.
- 使用六个声学和EGG指标进行了手术前和手术后两个月的客观语音质量评估.
- 创建了比较的语音地图,以分析干预前后的变化.
主要成果:
- 在甲状腺切除术后的大多数指标中,观察到表明语音质量下降的统计学上显著的变化.
- 个别的度量变化在效果大小上通常很小,缺乏临床相关性.
- 统计集群显示,变化主要与增加的声管不稳定性有关.
- 部分甲状腺切除术比全甲状腺切除术显示出更均的结果;外科手术期间的损伤类型没有影响语音质量.
结论:
- 甲状腺切除术与增加的声器不稳定性有关,影响声学和EGG语音指标.
- 聚类语音指标与患者报告的语音投诉的相关性比单个指标更强.

Larynx
1.5K
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,...

The Thyroid Gland
3.8K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Synthesis and Regulation of Thyroid Hormones
4.6K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Functions of Thyroid Hormones
2.7K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Tracheostomy: Procedure and Tubes
528
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Tracheostomy Care II: Procedure
165
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
