Laryngotracheal stenosis (Laryngo-: Glottic Stenosis; Subglottic Stenosis; Tracheal: narrowings at different levels of the windpipe) is a more accurate description for this condition when compared, for example to subglottic stenosis which technically only refers to narrowing just below vocal folds or tracheal stenosis.
Double aortic arch is a relatively rare congenital cardiovascular malformation. DAA is an anomaly of the aortic arch in which two aortic arches form a complete vascular ring that can compress the trachea and/or esophagus.
Incidence of congenital malformations associated with tracheal agenesis. Results were obtained from a total of 32 individual case studies. [11]The classic in-utero symptoms of tracheal agenesis are an absence of the trachea leading to congenital high airway obstruction syndrome, [12] [13] lung distention, polyhydramnios, heart malformations, heart displacement and hydrops fetalis.
A vascular ring is a congenital defect in which there is an abnormal formation of the aorta and/or its surrounding blood vessels. The trachea and esophagus are completely encircled and sometimes compressed by a "ring" formed by these vessels, which can lead to breathing and digestive difficulties.
More severe treatments include silicone stenting to prevent tracheal constriction, surgery to strengthen or attempt to rebuild the walls, continuous positive airway pressure [12] that has a machine blow small amounts of air into the trachea to keep it open (mainly at night), or a tracheostomy, [13] which is surgically inserted into the patient ...
Tracheomalacia is a condition or incident where the cartilage that keeps the airway (trachea) open is soft such that the trachea partly collapses especially during increased airflow. This condition is most commonly seen in infants and young children. [ 2 ]
They also proposed that shaping anterior costal cartilage grafts with flanges might prevent them from being displaced inward into the trachea. Cotton would later be the first to describe in detail the process of harvesting, carving and insetting an anterior costal cartilage graft along with his success using this technique in 11 children after ...
Subglottic stenosis is a congenital or acquired narrowing of the subglottic airway. [1] It can be congenital, acquired, iatrogenic, or very rarely, idiopathic. It is defined as the narrowing of the portion of the airway that lies between the vocal cords and the lower part of the cricoid cartilage. In a normal infant, the subglottic airway is 4. ...
