- Anatomy of the tracheobronchial tree has been described by Boyden et al in 1955 and several variants of bronchial position have been described. - Various theories for the pathogenesis of anomalous tracheobronchial development have been proposed. Anomalies resulting in anatomic variants of tracheobronchial anatomy are assumed to occur after the 28th day of gestation. - Congenital bronchial anomalies can be symptomatic, leading to recurrent pneumonia, hemoptysis or dyspnea. - Use of a uniform and comprehensive classification system is essential to describe congenital positional abnormalities of the tracheobronchial tree. - An abnormally positioned bronchus can be supernumerary or displaced. - A tracheal bronchus is the most frequent congenital bronchial positional anomaly and this term should only refer to a bronchus arising from the trachea or from the carina.
