In a study conducted on a child with oropharyngeal injuries caused by pressure water jet, further examination revealed contrast media extravasation in the nasopharyngeal region, deep maceration in the tonsillar region and pneumomediastinum in response to the only visible lesion is a small abrasion on the cheek (10).

Dyspnoea, haemoptysis, (massive) softtissue or mediastinal emphysema, pneumothorax, pneumomediastinum and emphsema are the common symptoms of tracheobronchial injuries.5 Although clinical manifestations may generally occur immediately, slower manifestation of symptoms such as subcutaneous emphysema, respiratory failure, pneumothorax and haemoptysis may delay recognition in some cases.5 The diagnoses of tracheobronchial injuries are not alwayseasy, since the actual presentation of the medical condition might be late and require serious medical attention, therefore the diagnoses could be delayed.
