Larynx01:21

Larynx

3.4K
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,...

The Thyroid Gland01:23

The Thyroid Gland

6.1K
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 Hormones01:20

Synthesis and Regulation of Thyroid Hormones

6.6K
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...

Physical Assessment of the Respiratory Tract IV: Auscultation01:28

Physical Assessment of the Respiratory Tract IV: Auscultation

1.6K
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

4.5K
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 Tubes01:28

Tracheostomy: Procedure and Tubes

2.0K
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...

Area of Science:

  • Otolaryngology
  • Speech and Language Pathology
  • Vocal Medicine

Background:

  • Thyroid surgery can lead to voice and singing difficulties.
  • A novel voice evaluation method was developed to assess these postoperative complications.

Purpose of the Study:

  • To introduce and evaluate the singing voice range profile (singing VRP) as a novel method for assessing voice function after thyroidectomy.
  • To compare the singing VRP with standard VRP and VHI-10 in evaluating postoperative vocal changes.

Main Methods:

  • The singing VRP was developed to record patients' singing voice ranges.
  • 128 patients' singing VRP, standard VRP, and VHI-10 were measured preoperatively and at 1 and 3 months post-thyroidectomy.
  • Subgroup analysis defined 'Collapsed' and 'Preserved' groups based on vocal range changes.

Main Results:

  • Singing fundamental frequency (F0) range decreased at 1 month post-surgery, improving by 3 months but remaining lower than pre-surgery.
  • The 'Collapsed' group showed significantly poorer voice quality and range compared to the 'Preserved' group.
  • The 'Preserved' group's singing F0 range recovered to preoperative levels by 3 months, unlike the 'Collapsed' group.

Conclusions:

  • Singing VRP parameters correlate with VHI-10 scores and standard VRP maximum F0.
  • Singing VRP aids in qualitatively classifying postoperative voice function when used with standard VRP.
  • Singing VRP serves as a valuable supplementary tool for evaluating the physiological and functional aspects of voice post-thyroidectomy.
