Summary
Tracheobronchomalacia (TBM) affects 9.38% of patients undergoing bronchoscopy. Age and anthracofibrosis are identified as key predictive factors for this respiratory condition.
Area of Science:
- Pulmonology
- Respiratory Medicine
- Medical Diagnostics
Background:
- Tracheobronchomalacia (TBM) involves softening of the trachea and bronchi, leading to respiratory issues.
- Limited data exists on TBM prevalence and associated risk factors.
- This study investigated TBM prevalence and predictive factors.
Purpose of the Study:
- To determine the prevalence of tracheobronchomalacia (TBM) in patients undergoing bronchoscopy.
- To identify demographic and clinical factors predictive of TBM.
- To explore the relationship between anthracofibrosis and TBM.
Main Methods:
- A cross-sectional study involving 1406 patients undergoing bronchoscopy.
- TBM defined by a ≥50% decrease in airway diameter during expiration.
- Patients were categorized into TBM cases and controls; data analyzed using logistic regression.
Main Results:
- The prevalence of TBM was 9.38% (132/1406); bronchomalacia was present in 16.66% of cases.
- Multivariable analysis identified older age (OR=1.02) and anthracofibrosis (OR=2.43) as significant predictors of TBM.
- A statistically significant association was found between age (P=0.03) and anthracofibrosis (P<0.0001) with TBM.
Conclusions:
- The study identified age and anthracofibrosis as significant predictive factors for TBM.
- Presence of anthracotic plaques may serve as a potential indicator for TBM.
- Findings contribute to understanding TBM epidemiology and risk stratification.

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

01:17Pulmonary Cycle: Exhalation
2.0K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
