Mohit Chawla right is one of the few fully trained interventional pulmonologists in the world. He and others at Memorial Sloan Kettering are leaders in developing new, minimally invasive techniques for managing tumors that develop in the chest. The trachea windpipe is the airway that extends downward from the larynx voice box and branches into two airways that lead to the lungs, called the left and right bronchi.

Mucopolysaccharidosis type II MPSII patients frequently suffer from dyspnoea caused by restrictive airway disease due to skeletal abnormalities as well as glycosaminoglycans GAG accumulation at different levels of the airway, including the trachea. In this study we describe the extent of the tracheal and bronchial narrowing, the changes in airway diameter during respiration and the effects of these obstructions on respiratory function in adult MPSII patients. Pulmonary function tests and in- and expiratory chest CT scans were obtained.

The upper airway is generally defined as the air passage segment that extends between the naso- or oropharynx and the carina. The longest segment of the upper airway-the trachea-begins at the inferior portion of the larynx and extends to the branch point of the main carina. The trachea has the potential to be a "forgotten zone" in differential diagnoses, as pathological processes involving this portion may not receive prominent clinical consideration in disorders presenting with respiratory symptoms and signs.

The trachea, known as the airway or windpipe, is a tube that starts under the larynx voice box and runs behind the breastbone. It then divides into two smaller tubes, bronchi which lead to the lungs. When breathing, a normal trachea widens and lengthens with each breath. Inflammation can cause scarring and narrowing of the trachea, while birth defects or injury can cause the trachea to become soft and floppy.

Idiopathic subglottic stenosis iSGS is a narrowing stenosis of a specific portion of the windpipe trachea known as the subglottis just below the vocal cords. Idiopathic means that the underlying cause of this narrowing is unknown. Most patients have scar tissue fibrosis and inflammation in the affected area.

Your trachea, or windpipe, is one part of your airway system. Airways are pipes that carry oxygen-rich air to your lungs. They also carry carbon dioxide, a waste gas, out of your lungs.

Tracheal stenosis is a narrowing of your tracheaor windpipe, due to the formation of scar tissue or malformation of the cartilage in the trachea. While mild narrowing in your trachea may never be identified, a significant narrowing of more than 50 percent of your airway can lead to serious complications. The three most prevalent causes of tracheal stenosis are:.

The upper airway is defined as the airway segment between the nose or mouth and the main carina, which is located at the lower end of the trachea. The central airways refer to the trachea and the main-stem bronchi. Unlike the lower conducting airways, such as the main, lobar, and segmental bronchi, the upper airway has no collateral ventilation. Therefore, obstruction of the upper airway or central airway is unique in that any obstruction, whether acute occurring within minutes or chronic developing over weeks or monthsmay be catastrophic.

Your trachea is also known as your windpipe. When you inhale air through your nose or mouth, it travels through your larynx, or voice box, and down your trachea. Your trachea branches into two tubes, called your bronchi, which deliver air to your lungs.

Your throat includes your esophagus, windpipe tracheavoice box larynxtonsils and epiglottis. Epiglottitis is a potentially life-threatening condition that occurs when the epiglottis — a small cartilage "lid" that covers your windpipe — swells, blocking the flow of air into your lungs. A number of factors can cause the epiglottis to swell — burns from hot liquids, direct injury to your throat and various infections. The most common cause of epiglottitis in children in the past was infection with Haemophilus influenzae type b Hibthe same bacterium that causes pneumonia, meningitis and infections in the bloodstream.
