Summary
Aerodynamic parameters objectively assess voice function. Key measures like phonation threshold pressure (PTP) effectively differentiate normal voices from disorders, aiding diagnosis.
Area of Science:
- Laryngology and Speech Science
- Acoustic Analysis
- Biomechanical Engineering
Context:
- Voice disorders significantly impact quality of life.
- Objective assessment tools are crucial for accurate diagnosis and treatment planning.
- Aerodynamic parameters offer a quantifiable method to evaluate vocal function.
Purpose:
- To assess the application and significance of aerodynamic parameters in voice function evaluation.
- To compare aerodynamic measurements between normal voices and various vocal fold pathologies.
- To determine the diagnostic utility of aerodynamic parameters in voice disorders.
Summary:
- Aerodynamic parameters, including phonation threshold pressure (PTP), phonation threshold flow (PTF), mean flow rate (MFR), subglottal pressure (SGP), and maximum phonation time (MPT), significantly differ between normal and disordered voices.
- Receiver operating characteristic (ROC) analysis indicated that PTP, PTF, SGP, MFR, MPT, and vocal efficiency (VE) have diagnostic utility, with PTP showing the highest area under the curve.
- Post-surgical assessment revealed significant changes in aerodynamic parameters after vocal cord polyp resection, highlighting their role in monitoring treatment outcomes.
Impact:
- Aerodynamic parameters provide objective and effective evaluation of vocal function variations.
- These parameters demonstrate significant auxiliary diagnostic value for voice disorders.
- The findings support the integration of aerodynamic assessment into routine clinical practice for voice evaluation.

01:21Larynx
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, corniculates, and...

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
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.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...

01:19Factors Affecting Pulmonary Ventilation
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...
