Presentation
Current therapeutic management depends on the extent, type, and severity of airway abnormalities noted and the clinical presentation. [ncbi.nlm.nih.gov]
However, expertise in this technique is not present nationwide. [jtd.amegroups.com]
Entire Body System
- Collapse
collapse (dynamic airway collapse) or pathologic collapse (EDAC) ( 1, 2 ). [jtd.amegroups.com]
RESULTS: Tracheal collapsibility varied widely among patients. Some had profound tracheal narrowing during quiet breathing, and others showed substantial collapse only during forced exhalation. [ncbi.nlm.nih.gov]
- Surgical Procedure
Hence, a surgical procedure could be considered as an alternative to stenting in such cases. [ncbi.nlm.nih.gov]
A person may be considered a candidate for this procedure depending on results of a short-term trial of stenting. Resection and reconstruction - this is a surgical procedure that may be used when TBD is more confined (focal). [rarediseases.info.nih.gov]
- Recurrent Infection
Twenty-two percent of respondents never considered TBM in patients with cough, sputum production, dyspnea, and recurrent infections. Thirty-eight percent did not proceed with further evaluation of TBM if pulmonary function tests were normal. [ncbi.nlm.nih.gov]

- Falling
Jennifer works diligently to bridge the gap in care, which so many patients and families fall into. [curetbm.org]
It is also possible to have complications that affect the function of the trach tube, such as the tube slipping or falling out of place, or that affect the windpipe or other airway structures. [nhlbi.nih.gov]
The biphasic flow-volume loop morphology is also characterized by a low maximum forced expiratory flow, which is followed by a rapid fall in flow, resulting in a plateau of very low flow for the remainder of exhalation. [rc.rcjournal.com]
Respiratoric
- Cough
CONCLUSION: Children with malacia have an increased likelihood of respiratory illness frequency, severity, significant cough, and tendency for delayed recovery. [ncbi.nlm.nih.gov]
[…] mouth Infants and children with primary TBM may also have a wheezing cough. [cedars-sinai.edu]
[11,12] Chang et al. have shown that an unusual quality of cough, such as a vibratory or brassy cough, has high levels of sensitivity and specificity for bronchoscopically proven malacia. [13] Despite these advances in knowledge, missed diagnoses brought [medscape.com]
- Dyspnea
Improvement of dyspnea is the most consistent metric of treatment effect, likely because dyspnea is the most common presenting complaint in patients with diffuse TBM and because of the immediate effect of the stent on expiratory airflow. [jtd.amegroups.com]
Thirty-three patients (94%) presented with severe dyspnea, 26 patients (74%) with uncontrollable cough, and 18 patients (51%) reported recurrent pulmonary infections. [ncbi.nlm.nih.gov]
Case Report A76-year-old female was admitted to our hospital with complaints of cough, dyspnea, night sweats, and weight loss. She reported cough and progressive dyspnea for the preceding 10 years. [karger.com]
- Pneumonia
TBM results in chronic cough, poor mucous clearance, and recurrent pneumonias. Apparent life-threatening events or recurrent pneumonias may require surgery. [ncbi.nlm.nih.gov]
The most common complication was pneumonia (2/9, 22.2%) Median length of hospital stay was 7.5 days and no patients died postoperatively. [meetings.westernthoracic.org]

The usual symptom of tracheomalacia is inspiratory stridor or laryngeal crow. Tracheomalacia may be congenital or acquired. [jpalliativecare.com]
The subsequent clinical course was complicated by recurrent stridor, upper airway obstruction, and periods of profound oxygen desaturation. [fn.bmj.com]
- Pulmonary Disorder
Also, the majority of previous studies review TBM in patients with multiple pulmonary disorders. There is marked variability in the incidence of TBM in the literature. [ispub.com]
Gastrointestinal
- Failure to Thrive
However, intervention may be needed in children with episodes of airway obstruction, frequent infections, respiratory failure, and/or failure to thrive. [rarediseases.info.nih.gov]
His additional morbidities included tetralogy of Fallot with absent pulmonary valve that had previously been repaired, multiple venous thromboses, failure to thrive, Pseudomonas mediastinitis, and a congenital right upper extremity disorder. [stm.sciencemag.org]

Neurologic
- Irritability
In adults TBM is more often seen in smokers with chronic irritation of the airway, particularly middle aged or older men with COPD. [theasthmacenter.org]
[…] causes: Damage to the windpipe during a tracheostomy, where an incision is made into the windpipe and a tube is inserted to help with breathing Tracheal fractures Tumors pressing on the windpipe Thyroid tumors Dilated aortic or pulmonary arteries Chronic irritation [cedars-sinai.edu]
Some masks can cause irritation. Your doctor can help you find ways to relieve these symptoms and adjust to using your CPAP machine. [nhlbi.nih.gov]
However, risk factors for TBM include tracheal fractures, tracheostomy, tumors, and chronic irritation from conditions such as asthma, coughing and/or second hand smoke. [curetbm.org]
Workup
In this report, we review the treatment of TBM, including preoperative workup, intraoperative anesthesia management, and surgical technique for posterior splinting tracheobronchoplasty. [ncbi.nlm.nih.gov]
With increased awareness of TBM as an independent cause of clinical symptoms and functional impairment, the need for a standard diagnostic workup becomes more important. [rc.rcjournal.com]
As part of their diagnostic workup, all infants had structurally normal hearts on echocardiogram, normal sweat tests, and normal immune function. Gastro-oesophageal reflux was excluded or treated if confirmed. [fn.bmj.com]
Pulmonary function testing is often unhelpful in screening patients during the initial diagnostic workup. [jtd.amegroups.com]
Treatment
[…] appropriate treatment is important. [10] Last updated: 3/22/2018 Research helps us better understand diseases and can lead to advances in diagnosis and treatment. [rarediseases.info.nih.gov]
If found, these diagnoses require adequate treatment prior to surgical evaluation. [jtd.amegroups.com]
MATERIALS AND METHODS: Fifteen patients who had received treatment in our interventional pulmonology unit were analyzed. We analyzed the techniques used, stent duration, complications, and long-term treatment success retrospectively. [ncbi.nlm.nih.gov]
Prognosis
In general, the prognosis is good in children with primary TBM who do not have any associated problems. [rarediseases.info.nih.gov]
Treatment and prognosis In most cases, no treatment is required or offered. [radiopaedia.org]

Etiology
This paper describes our experience standardizing the approach to these complex patients whose backgrounds include different disease etiologies, as well as a variety of comorbid conditions. [ncbi.nlm.nih.gov]
Etiology and classification of ECAC The cause of diffuse TBM is often unknown, but it is frequently seen in patients with common respiratory conditions such as asthma, chronic bronchitis and emphysema. [jtd.amegroups.com]
The underlying etiology is one of reduced or abnormal connective tissues in the trachea, particularly the cartilaginous rings. [radiopaedia.org]
Epidemiology
This review discusses the physiology, histopathology, epidemiology, and clinical features of TBM; it also describes current methods of diagnosis, available therapies, and postoperative imaging evaluation. [ncbi.nlm.nih.gov]
Epidemiology History : earliest references to tracheomalacia are from the 1930’s-1940’s, describing congenital thoracic vascular abnormalities which resulted in tracheal obstruction Prevalence : acquired tracheobronchomalacia is more common than congenital [mdnxs.com]

Pathophysiology
[…] of Medicine, University of Chicago Pritzker School of Medicine, Chicago, IL 60637, USA. [email protected] Abstract Tracheobronchomalacia and excessive dynamic airway collapse are morphologic types of expiratory central airway collapse with specific pathophysiology [ncbi.nlm.nih.gov]
It is often mentioned, incidentally and interchangeably, with tracheobronchomalacia (TBM), but it is pathophysiologically and morphologically distinct from TBM. [shortnessofbreath.it]
Prevention
The stenting technique used did not prevent the development of respiratory failure and death in this patient. Hence, a surgical procedure could be considered as an alternative to stenting in such cases. [ncbi.nlm.nih.gov]
