After a minor blow to the neck from the handlebars of a bike, a 5-year-old boy developed a massive subcutaneous emphysema with respiratory distress. Orotracheal intubation was performed. A computed tomography (CT) scan of the neck and thorax showed a pneumomediastinum and a bilateral pneumothorax. No injury to the large airways was identified. The patient was stabilized by insertion of chest tubes and controlled ventilation. The endoscopic examination of the trachea revealed a tear of the pars membranacea, which was successfully treated conservatively. The specific features of the injury and the airway management are discussed based on a review of the current literature.
