Laryngotracheal stenosis

Laryngotracheal stenosis (pronounced: la-ring-go-tray-key-al sten-oh-sis) is a medical condition characterized by a narrowing of the larynx and trachea, the air passages leading from the mouth and nose to the lungs.

Etymology

The term "Laryngotracheal stenosis" is derived from three Greek words: "laryngo" meaning larynx, "trachea" meaning windpipe, and "stenosis" meaning narrowing.

Definition

Laryngotracheal stenosis is a condition where the larynx or trachea becomes narrowed due to inflammation, injury, or a congenital condition. This can lead to difficulty breathing and other respiratory symptoms.

Symptoms

Common symptoms of laryngotracheal stenosis include dyspnea (shortness of breath), stridor (a high-pitched wheezing sound), and cough. In severe cases, it can lead to respiratory failure.

Causes

Laryngotracheal stenosis can be caused by a variety of factors, including prolonged intubation, trauma to the throat, infections, and certain autoimmune diseases such as Wegener's granulomatosis.

Treatment

Treatment for laryngotracheal stenosis typically involves surgery to widen the airway. This can be done through a procedure called a tracheostomy, where a hole is made in the neck to bypass the narrowed area. Other treatments may include balloon dilation, laser surgery, or stent placement.
