The occurrence of tracheoesophageal fistula (TEF) in children is commonly attributed to the presence of foreign bodies. This paper presents a unique case admitted to the Children's Hospital of Nanjing Medical University on August 9, 2022, where a plastic fragment resembling a doll's eye was identified as the precipitating factor. The report investigates the unusual trajectory of this case-examining the pathway through which the foreign body became lodged in the trachea, followed by the subsequent development of TEF-and provides valuable insights into its pathogenesis and clinical significance.
