Acute traumatic osseous and cartilaginous injuries to the larynx are rare but have a high morbidity and mortality. This study aims to identify fracture and soft tissue injury patterns in laryngeal trauma and explore their associations with patient demographics, mechanisms of injury, and urgent airway and surgical intervention.
PurposeAcute traumatic osseous and cartilaginous injuries to the larynx are rare injuries presenting to the emergency department. Despite the low reported incidence, laryngeal trauma carries a high morbidity and mortality. The purpose of this study is to identify fracture and soft tissue injury patterns in laryngeal trauma and explore associations with patient demographics, mechanisms of injury, urgent airway and surgical intervention.MethodsA retrospective review of patients with laryngeal injury who underwent multidetector computed tomography (MDCT) imaging was performed. The CT findings of laryngeal and hyoid fracture location, fracture displacement, and soft tissue injuries were recorded. Clinical data including patient demographics, mechanisms of injury, frequency of airway and surgical intervention were also recorded. Correlation of imaging characteristics with patient demographics, mechanism of injury and interventions were assessed for statistical significance using & chi;(2) and Fisher's exact tests.ResultsThe median patient age was 40 years old with a strong male predominance. The most common mechanisms of injury included motor vehicle collisions and penetrating gunshot wounds. Thyroid cartilage fractures were the most common fracture type. Findings of fracture displacement and airway hematoma had a higher correlation with requiring urgent airway management.ConclusionRadiologists' early recognition and prompt communication of laryngeal trauma to the clinical service is important to reduce associated morbidity and mortality. Displaced fractures and laryngeal hematomas should be promptly conveyed to the clinical service as they are associated with more complex injuries and higher rates of urgent airway management and surgical intervention.
