Fiberoptic bronchoscopic treatment, including balloon dilation and steroid injection, effectively alleviates subglottic stenosis symptoms. This minimally invasive approach reduced the need for repeat procedures in patients with this airway narrowing.
Area of Science:
- Pulmonology
- Otolaryngology
- Interventional Bronchoscopy
Background:
- Subglottic stenosis causes airway narrowing below the vocal cords, leading to significant breathing difficulties.
- Effective management of subglottic stenosis is crucial for improving patient quality of life.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

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...

The Bronchial Tree
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...
