A 7 week old infant was admitted with respiratory failure. Chest X‐ray showed an atelectatic right upper lobe, herniation of right middle and lower lobe into the left thorax, and compression‐atelectasis of the left lung. Thoracic CT showed complete occlusion of the right superior bronchus with a radiopaque foreign material. Six weeks prior, an impression for a palate plate using polyvinylsiloxane was taken. The material was removed with a rigid endoscopy, in readiness of extracorporeal oxygenation in case of tracheal obstruction or bronchial rupture. After 4 months of follow‐up a hyper reactive airway with recurrent upper and lower airway infections remains.
