A total of 292 cases of bronchial foreign bodies, with the age of 15 years or younger, were compiled from Japanese literatures during the period from 1950 to 1978 and analysed of the involved site by classifying them according to the age, sort of foreign bodies and duration of staying period. It was found that the foreign bodies were more often seen in the right bronchus, with no correlative relation between the age and the involved site. In cases of short staying period less than one week, the foreign bodies were seen overwhelmingly in the right side, with a decreasing tendency in the difference in affected sites with the prolongation of the staying period.
The laterality of the bronchial foreign bodies may be determined by various combinations of conditions of foreign bodies and those of hosts. We studied the tracheal curvature, branching angle of bronchi, inner diameter of bronchi and the posture of the patient as the factors giving influences on the laterality of the bronchial foreign bodies. Moreover, the relation between the staying period and the involved side was also reviewed.
