Larynx01:21

Larynx

4.2K
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,...

Respiratory System Abnormal Finding II: Palpation and Auscultation

1.4K
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Common Respiratory Disorders01:31

Common Respiratory Disorders

1.3K
Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Physical Assessment of the Respiratory Tract IV: Auscultation

2.2K
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.

The Auditory Ossicles01:11

The Auditory Ossicles

3.0K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Physical Assessment of the Respiratory Tract I: Health History01:28

Physical Assessment of the Respiratory Tract I: Health History

833
Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
Health history and...

Summary

Vocal cord dysfunction (VCD) causes upper airway obstruction and is often misdiagnosed as asthma. Early diagnosis and treatment of VCD significantly improve patient symptoms and reduce reliance on asthma medications.

Area of Science:

  • Otolaryngology
  • Pulmonology
  • Allergy and Immunology

Background:

  • Vocal cord dysfunction (VCD) is an upper airway disorder causing transient glottic constriction.
  • VCD symptoms, including respiratory and laryngeal issues, are frequently misdiagnosed as asthma, leading to significant patient morbidity.
  • VCD can mimic allergic conditions and may coexist with asthma, complicating diagnosis.

Purpose of the Study:

  • To highlight the diagnostic challenges associated with vocal cord dysfunction.
  • To emphasize the importance of recognizing VCD as a distinct upper airway disorder.
  • To underscore the benefits of accurate VCD diagnosis and treatment.

Main Methods:

  • Literature review on vocal cord dysfunction diagnosis and management.
  • Analysis of clinical presentations and misdiagnosis patterns of VCD.
  • Evaluation of treatment outcomes for patients with diagnosed VCD.

Main Results:

  • VCD is often misdiagnosed as asthma due to overlapping symptoms.
  • Intermittent symptomatology and underappreciation of VCD contribute to diagnostic delays.
  • Accurate diagnosis and treatment of VCD lead to substantial symptom improvement.

Conclusions:

  • Vocal cord dysfunction requires greater medical community awareness for accurate diagnosis.
  • Timely diagnosis and intervention for VCD can significantly improve patient quality of life.
  • Effective VCD management can reduce unnecessary asthma medication use.
