Unrecognized bronchial foreign bodies (Fbs) cause irreversible changes in the airways. However, Vie exact course of these changes is not well-known. We developed an animal model of bronchial obstruction to radiologically and histopathologically assess the development of postobstructive pulmonary changes. A piece of peanut was placed in the airways of 21 rabbits through a 2.5-mm rigid bronchoscope. Animals were divided into three groups (groups I-III) that were sacrificed on day 3,10, and 30 after Fb placement, respectively.
