External laryngeal trauma and thyroid cartilage fracture: A literature review

Abstract

The laryngeal trauma constitutes a group of infrequent lesions, but with great clinical importance, given its high morbidity and mortality. It requires a high level of suspicion, since many of these injuries may go unnoticed at the initial evaluation. It should be suspected in every patient presenting with cervical trauma and symptoms ranging from dysphonia and anterior cervical pain, to dyspnea or even severe respiratory distress, due to obstruction of the airway. The approach of these patients should begin with the evaluation of the airway and ensure its stability, to then focus on the diagnosis and spe- cific management of the lesions. We present an updated literature review regarding the mechanisms of trauma, clinical presentation, diagnosis, classification and management.
