Methods 218 of airway foreign bodies confirmed by bronehoscopy were retrospectively analyzed in terms of clinical and imaging data. Results 218 patients included 140 males and 78 females. Their ages ranged 6 months to 12 years （mean, 19.2 months）. All patients had conventional radiographs on frontal chest films, neck lateral films and fluoroscopy. 34 cases underwent 64-slice spiral chest CT examination. According to the location of the foreign bodies, 29 cases were in throat and subglottic, 55 cases in trachea and 134 cases in bronchus （79 cases in the right, 55 cases in the left）. According to the character of the foreign bodies, 5 cases were metal, 29 cases in bone, 93 cases in peanuts, 59 cases in seeds, 22 cases in fruits and vegetables and 10 cases in others respectively. Thirty-fourcases showed a direct sign of the foreign body and 177 cases showed the indirect signs. 34 cases on CT examination directly were showed foreign body in the tracheal bronchi.
