In patients with TBM in one study, the number of longitudinal elastic fibers in the pars of membranacea was reduced throughout the whole trachea.People with heritable connective tissue disorders like Ehlers–Danlos syndrome seem to have at an increased risk of both congenital and acquired TBM, although the extent of that risk is unknown. There have been studies linking long-term use of inhaled Corticosteroids to Tracheobronchomalacia. Diagnosis
Diagnosis is conducted according to the severity of the symptoms. Initially pulmonary function tests are administered. These tests include the lungs capability of air intake and outtake, and gas flow of oxygen and carbon dioxide between the body and environment. Following these function tests a special type of Chest CT scan or a bronchoscopy will be ordered. The results of the scan and bronchoscopy will display the status of the condition. A mild case of tracheobronchomalacia would be if the patients trachea condenses 50% of its normal space when exhaling. Moderate tracheobronchomalacia would be 25% of the normal trachea space constricting and a severe case would be if the walls touch each other.Tracheobronchomalacia is thought to be underdiagnosed as mild cases may be asymptomatic and symptoms are often mistaken for more common respiratory conditions like Athsma and Chronic obstructive pulmonary disease. Treatment
To properly treat a patient with tracheobronchomalacia, the subtype must be determined (primary or secondary). After the type is named, the cause must be identified, whether it is from genetics, a trauma accident, or chronic tracheal illness.
