Tracheomalaciaor sometimes described as tracheobronchomalaciais a common incidental finding on imaging of the chest of older patients and manifests as an increase in tracheal diameter as well as a tendency to collapse on expiration. Some authors consider an overlap with the term " excessive dynamic airway collapse ". Tracheomalacia can be broadly considered as being congenital or acquired.
Volume 6, Number 10, Octoberpages Down syndrome is a common chromosomal abnormality associated with many different structural anomalies. Tracheomalacia results in tracheal collapse when increased airflow is demanded due to the flaccidity of the tracheal support cartilage.
Tracheobronchomalacia in adults is uncommon and often an incidental finding on a chest CT. These patients are often miserable and there is often a delay in diagnosis as many clinicians are not familiar with this uncommon disease. In general it is best to refrain from operating on those with significant COPD unless one is quite convinced that the tracheobronchomalacia is very dominant. The evaluation process starts with a high quality dynamic chest CT with inspiratory and expiratory views to determine the degree of tracheobronchomalacia, whether it extends to the major bronchi, and to screen for other lung diseases Figure 1.
Acquired tracheomalacia is a weakness and floppiness of the walls of the windpipe trachea, or airway. It develops after birth. Acquired tracheomalacia is very uncommon at any age.
The diagnosis is often overlooked, as chest radiography appears normal, and the role of invasive diagnostic testing for this diagnosis is not well described in the ICU setting. The prevalence and risk factors for STM are not known, and computed tomography CT based diagnostic criteria for ventilated patients are not well studied. METHODS: Patients admitted between January and Decemberwith respiratory failure and who failed ventilator discontinuation or required reintubation, were screened for the presence of any tracheal collapse, utilizing prior CT of the chest.
Tracheomalacia - acquired Definition Acquired tracheomalacia is a weakness and floppiness of the walls of the windpipe trachea, or airway. It develops after birth. Congenital tracheomalacia is a related topic.
Tracheobronchomalacia TBM is a rather underdiagnosed endobronchial disease which treatment depends on the severity of symptoms as a consequence of severe dynamical tracheal occlusion. To this date there is no consensus regarding the therapeutic approach, hence, new state-of-the-art techniques should be taken into consideration. The spectrum of central airway expiratory dynamic obstruction includes TBM and excessive or hyperdynamic airway collapse.

The trachea windpipe is the airway, a tube made up of cartilage the firm tissue in the ear which starts just below the larynx voice box and continues down behind the breastbone then splits into two smaller tubes, called bronchi, which lead to each lung. With normal breathing, as air is drawn into the lungs, the trachea grows wider and longer.
Tracheomalacia is a congenital condition, meaning it is present at birth. It is a condition characterized by a soft and pliable windpipe trachea instead of rigid windpipe. This causes breathing difficulties because your child's airway doesn't stay remain open as it should especially when coughing, feeding or heavy breathing.
