Severe laryngeal injuries masked by fractured mandible.

UNLABELLED: A 17-year-old male was referred to the maxillofacial department regarding a fractured mandible. Airway compromise was suspected as a result of neck swelling, stridor, haemoptysis and surgical emphysema. Severe laryngeal injuries were diagnosed, including a fractured hyoid. His treatment and outcomes are summarized, with discussion of aetiology, symptoms, diagnosis and treatment of laryngeal injuries, including urgent airway management, if necessary. The risks and complications of delayed diagnosis and treatment are discussed, particularly if symptoms are delayed or the injury is masked by facial fractures. A high index of suspicion and thorough examination are emphasized in all head and neck trauma patients.

CLINICAL RELEVANCE: Any dental professional may be the first to see a trauma victim. It is important to be aware of the risk of life-threatening laryngeal injuries which may be delayed in diagnosis, owing to later development of symptoms and signs or to more obvious injuries.
