title: Tracheobronchial foreign body aspiration in children.
abstract: In this retrospective study, we reviewed the demographic and radiographic findings of 155 children with bronchoscopy-proven tracheobronchial foreign body aspiration (FBA). Two thirds of the patients were male, and most were children between 1 and 2 years of age. An aspirated peanut accounted for one third of all cases. Foreign body location was distributed nearly evenly to the right and left primary bronchi; tracheal foreign body was noted in 16 patients. The most frequent symptoms of FBA were cough (85 patients) and wheezing (60 patients). Although most patients were seen within 1 day of aspiration, 30 patients had symptoms that lasted at least 1 week before diagnosis. The most common radiographic findings were unilateral or segmental hyperlucency (59) or atelectasis (38). The trachea was the site of the foreign body in one half of children with a normal chest radiograph and FBA.
