    ObjectiveTo review and discuss the existing research on the pathophysiology, impact and management of inhalational injury on the larynx and lower respiratory tract.Data SourcesA literature search was conducted on the PubMed, MedLine, Embase, Web of Science and Google Scholar databases based on the keywords "airway burn", "inhalational injury" and "larynx".Review MethodsInclusion criteria included English language studies containing original and review data on airway injury. Data was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.ConclusionsAbnormal laryngeal and lower airway findings are common in burns patients and the incidence tends to increase with severity of the burns. Most patients with abnormal findings remain dysphonic decades after the initial injury. Larynx, the inlet to the airway, is exposed to the most intense thermal damage and highest concentration of chemical in inhalational injury. Airway injury is common and may result in long term morbidity. Healing of this tissue architecture is prolonged and different from cutaneous burn. Many patients receive prolonged intubation for medical complications that arise due to the burn injury. The degree of subglottic damage, however, is more extensive and occurs sooner compared with those without inhalational injuries.Implications For PracticeWith advances in acute medical and surgical management of burn and inhalational injury, airway injury is an important secondary outcome with lasting impact. Awareness of these potential complications and early involvement of medical and allied health team are important steps in improving patient care. A multi-disciplinary approach to management will optimise the short and long-term morbidity management and ultimately our patients' quality of life.Copyright © 2018 Elsevier Ltd and ISBI.
