Core Tip

Core Tip: Excessive dynamic airway collapse (EDAC) is a less recognized condition with expiratory airflow limitations that is caused by laxity in the posterior membranous wall, leading to the excessive narrowing of the central airway lumen. The overlap of EDAC symptoms with chronic obstructive pulmonary disease and asthma often delays the accurate diagnosis. This mini-review discusses the role of dynamic imaging modalities in EDAC diagnosis and the different approaches in the management of EDAC, ranging from conservative treatments to surgical options like tracheobronchoplasty. Standardizing diagnostic criteria, tailoring management strategies, and increasing research are crucial in improving patient outcomes in EDAC.
