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.
Bronchomalacia can best be described as a birth defect of the bronchus in the respiratory tract. Congenital malacia of the large airways is one of the few causes of irreversible airways obstruction in children, with symptoms varying from recurrent wheeze and recurrent lower airways infections to severe dyspnea and respiratory insufficiency.
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] The usual symptom is stridor when a person breathes out. This is usually known as a ...
A collapsed trachea is formed as a result of defect in the cartilage, that makes the cartilage unable to support the trachea and results in dry hacking cough. In this condition there can be inflammation of the linings of the trachea. If the connective nerve tissues in the trachea degenerate it causes tracheomalacia.
The relative similarities between the different subtypes of the disease suggest that there is a common stage at which the development is hindered. In normal embryogenesis, the trachea differentiates from the foregut during the fourth week of gestation. The respiratory diverticulum, a ventral projection formed from the foregut, appears.
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 ...
Bronchiolitis typically affects infants and children younger than two years, principally during the autumn and winter. [15] It is the leading cause of hospital admission for respiratory disease among infants in the United States and accounts for one out of every 13 primary care visits. [8]
Tracheobronchomegaly is a very rare congenital disorder of the lung primarily characterized by an abnormal widening of the upper airways. [2] The abnormally widened trachea and mainstem bronchi are associated with recurrent lower respiratory tract infection and copious purulent sputum production, eventually leading to bronchiectasis and other respiratory complications.
