What is subglottic stenosis?

Subglottic stenosis (SGS) is a narrowing of the airway below the vocal cords (subglottis) and above the trachea. Subglottic stenosis will involve narrowing of the cricoid, the only complete cartilage ring in the airway.

How do you fix subglottic stenosis?

Several different surgical procedures have been used to treat idiopathic subglottic stenosis, but are generally categorized into: 1) endoscopic dilation of the tracheal stenosis (accomplished with rigid instruments or inflatable balloons); 2) endoscopic resection of the stenosis (with prolonged medical therapy after …

Can tracheostomy cause subglottic stenosis?

Acquired subglottic stenosis is secondary to localized trauma to subglottic structures. Usually, injury is caused by endotracheal intubation or high tracheostomy tube placement. If irritation persists, the original edema and inflammation progress to ulceration and granulation tissue formation.

What causes stenosis of the throat?

Tracheal stenosis can also develop from a number of other causes, including: External injury to the throat. Benign or malignant tumor pressing on the windpipe. Certain autoimmune disorders, such as polychondritis, sarcoidosis, papillomatosis, amyloidosis, or Wegener’s granulomatosis.

What can cause subglottic stenosis?

This most commonly occurs due to infection, trauma, or problems associated with intubation (a breathing tube inserted into the airway). These issues can cause scar to form in the airway that causes narrowing.

Can acid reflux cause tracheal stenosis?

Many authors have implicated gastroesophageal reflux disease (GERD) as a cause of idiopathic tracheal stenosis [2, 3]. We present a case of tracheal stenosis that improved with clinical treatment of GERD.

Does GERD cause subglottic stenosis?

Gastroesophageal reflux disease as a likely cause of “idiopathic” subglottic stenosis.
