Summary
Tracheostomy significantly alters nasal lining, causing epithelial atrophy and reduced glands in 80% of patients. This study highlights microanatomical changes in the nasal airway due to airflow deprivation.
Area of Science:
- Otolaryngology
- Respiratory Medicine
- Histopathology
Background:
- Tracheostomy is a common procedure for airway management.
- The impact of tracheostomy on nasal mucosa histology is not well understood.
Purpose of the Study:
- To evaluate histological changes in the nasal mucosa following tracheostomy.
- To assess the effects of nasal airflow deprivation on nasal airway microanatomy.
Main Methods:
- Prospective observational study of 30 patients undergoing tracheostomy.
- Anterior rhinoscopy and inferior turbinate biopsies performed pre- and post-procedure.
- Histological comparison of nasal mucosal biopsies at baseline and four-week follow-up.
Main Results:
- Significant epithelial atrophy observed in 80% of subjects (pseudostratified to flattened single layer).
- Marked reduction in seromucinous glands in 80% of subjects.
- Stromal fibrosis noted in 43.3% of subjects at follow-up.
Conclusions:
- Tracheostomy leads to significant microanatomical changes in the nasal airway, likely due to airflow deprivation.
- Further research in larger populations with extended follow-up is warranted to understand causation and implications in nasal pathology.

01:21Tracheostomy Decannulation
164
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

01:28Tracheostomy: Procedure and Tubes
574
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

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...

01:16Tracheostomy Care I: Pre-procedural Steps
185
A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.

179
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
