Two infants inhaled eggshell fragments. The first aspirated a small fragment into the upper part of the trachea and resuscitation attempts resulted in descent of the foreign body to the right lower lobe bronchus. Two attempts at bronchoscopy were unsuccessful and spontaneous disintegration occurred. The second infant aspirated an eggshell fragment to the entrance of the larynx where it was removed by laryngoscopy. Laryngeal or tracheal foreign body in infants under 1 year of age are rare, and the diagnosis and removal are difficult.
