Larynx

Larynx

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,...

Chronic Obstructive Pulmonary Disease

Chronic Obstructive Pulmonary Disease

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Chronic Obstructive Pulmonary Disease-I: Introduction

Chronic Obstructive Pulmonary Disease-I: Introduction

Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

COPD: Pathogenesis and Clinical Features

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Background:

Professional voice users (PVUs) rely on vocal quality for work.
Dysphonia, or voice disorders, can significantly impact PVUs' careers.
Identifying risk factors is crucial for preventing and managing these disorders.

Purpose of the Study:

To identify risk factors and causes of voice disorders in occupational voice users.
To analyze socio-epidemiological characteristics of patients with dysphonia.
To investigate associations between lifestyle, medical conditions, and voice quality.

Main Methods:

Retrospective study of 145 occupational voice users treated for dysphonia (2019-2024).
Data collection included demographics, symptom duration, tobacco use, medical history, and vocal fold analysis.
Patients stratified by age, profession, and dysphonia cause.

Main Results:

Dysphonia is more prevalent in females.
Age and hyperthyroidism are significantly associated with dysphonia causes.
Smoking is prevalent but causality with voice parameters requires further study.
No significant link found between infections or allergies and dysphonia.
Treatment varies by gender; males more likely to have surgery, females conservative therapy.
Symmetric vocal fold vibration observed in 85.5%; regular vibration in 53.1%.

Conclusions:

Systematic otolaryngologic examinations are recommended for PVUs.
Mandatory education on voice use, hygiene, and smoking's effects is essential.
Preventive measures can mitigate voice disorders in occupational voice users.
