Summary
Estimated subglottal pressure was higher in voice disorder patients, but mean airflow rate did not differ from controls. Aerodynamic measures like MFR and est-Psub do not determine voice disorder diagnosis.
Area of Science:
- Laryngology
- Speech-Language Pathology
- Acoustic Analysis
Background:
- Previous research explored aerodynamic profiles in muscle tension dysphonia.
- The relationship between mean airflow rate (MFR) and estimated subglottal pressure (est-Psub) in various voice disorders requires further investigation.
Purpose of the Study:
- To compare MFR and est-Psub between individuals with voice disorders and a healthy control group.
- To investigate variations in MFR and est-Psub pairings within the voice disorder population.
- To determine if these variations are diagnosis-specific.
Main Methods:
- Retrospective chart review of 192 patients undergoing voice assessment.
- Aerodynamic measures including MFR and est-Psub were analyzed.
- Statistical analyses included t-tests, cluster analysis, and ANOVA.
Main Results:
- Individuals with voice disorders exhibited significantly higher mean est-Psub compared to controls (P < 0.001).
- No significant difference in MFR was observed between voice disorder patients and controls (P < 0.59).
- Nine MFR and est-Psub pairings were identified, with no significant diagnostic specificity.
Conclusions:
- Mean airflow rate and estimated subglottal pressure are not definitive diagnostic indicators for voice disorders.
- Findings align with previous research suggesting MFR and est-Psub do not determine diagnosis.
- Further research may explore other aerodynamic or acoustic parameters for diagnostic differentiation.

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:

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
2.8K
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.

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,...

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.
