Decoding airway granulogenesis in children: unveiling risk factors for tracheobronchial foreign body aspiration and complications

Tracheobronchial foreign bodies primarily develop in male children under the age of 3 and often lead to various complications. The time of foreign body insertion and the release of oil from the obstructed foreign body have been identified as high-risk factors for the development of tracheobronchial granulation tissue. When the time of foreign body insertion without oil release exceeds 99.98 h or when the time of foreign body insertion with oil release exceeds 47.94 h, tracheobronchial granulation formation strongly suggests that the child is at high risk of developing airway granulation. In such cases, family members must implement increased supervision of the child to prevent choking. Medical professionals should obtain a detailed medical history of the affected child and accordingly select the most appropriate method to promptly remove the foreign body to resolve the issue of airway obstruction and reduce the likelihood of pulmonary complications in the child.
