Subglottic Stenosis

by admin on November 30, 2017

Subglottic Stenosis is the narrowing of the subglottic airway, which is located below the vocal cords. The subglottic airway is the narrowest part of the air passage and, housed in the cricoid cartilage, it has no room for expansion and pliability. This narrowing condition can either be congenital, a birth defect, or acquired due to of trauma or intubation. This condition is far more common in premature infants, and typically results from prolonged intubation. Rated on a scale of 1 to 4, with 1 being a less than 50 percent blockage and 4 being a total blockage, subglottic stenosis is the third most common congenital airway defect in children.

While a number of treatments, such as trachea stents and steroids, have been unsatisfactorily administered in the past, one of the most effective treatments doctors have today for this condition is a surgical procedure known as a cricoid split. This surgery cuts across the cricoid cartilage, which is the ring of cartilage around the trachea, to allow for expansion of the subglottic airways. Depending on the degree of stenosis, cartilage may also be grafted on to ensure the wider opening remains.
