Autopsy & Case Reports
|July 18, 2024
Summary
Laryngeal granulomas, often caused by intubation, can lead to serious voice changes and breathing difficulties. In rare cases, these benign lesions can be fatal, as seen in a case following laryngeal polyp removal.
Area of Science:
- Otolaryngology
- Pathology
Background:
- Laryngeal granulomas, including vocal process or post-intubation granulomas, are benign inflammatory lesions.
- Etiologies include chronic irritation from endotracheal intubation, vocal cord trauma, and gastroesophageal reflux disease.
Observation:
- These lesions can develop postoperatively following mucosal injury from orotracheal intubation.
- Clinical signs such as voice alteration and dyspnea may manifest 1-4 months after extubation.
Findings:
- Laryngeal granulomas, though typically benign, carry a risk of airway compromise, including asphyxia.
- A rare fatal case of glottic granuloma occurred post-surgery for a laryngeal polyp, linked to prior intubation injuries.
Implications:
- Highlights the potential severity of laryngeal granulomas, even after initial treatment.
- Underscores the importance of recognizing granuloma risks associated with intubation history.
- Suggests vigilance for delayed airway complications in patients with relevant intubation history.

Larynx
1.4K
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,...

Acute Respiratory Failure-III
170
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Pneumothorax-I
190
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Trachea

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...

Pneumothorax-II
135
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Other Pulmonary Disorders

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.
