a) Chest radiograph showing a radiopaque object in the right lower lung field (dotted circle). The inset image shows the retrieved dental prosthesis, 10 mm x 5 mm, with a scale bar. b) The bronchoscopic image shows mucosal redness, edema, and granuloma formation in the right basal bronchus. c) A bronchoscopic image taken after 4 days of prednisolone administration shows improvement of the mucosal inflammation.

A chest radiograph showed a small radiopaque object (Fig. 1A). Since the right basal bronchus demonstrated mucosal redness, edema, and granuloma formation (Fig. 1B) and the FB was lodged in the periphery of B9, the object could not be visualized through a bronchoscope. By the second bronchoscopy, swelling of the bronchial mucosa was improved (Fig. 1C), but the FB was still not visible. In this way, we retrieved a dental prosthesis, 10 mm x 5 mm in size, without bleeding (Fig. 1A).

A chest radiograph showed a radiopaque object in the right pulmonary hilum (Fig. 2). We successfully retrieved a dental prosthesis, 20 mm x 10 mm (Fig. 2), without dropping it in the oral cavity, and without any other adverse event.

To encircle the FB with the loop under fluoroscopic observation, we bend the neck of the bronchoscope toward the opposite side of the inserted loop and tighten the loop slowly (Fig. 3).
