Injury above the vocal cords is a clinical manifestation of open neck injury. Arytenoid cartilage dislocation and hematoma above and below the vocal folds or vocal folds are also associated with hoarseness or loss of voice, sometimes with laryngeal tinnitus on inspiration. Patients often complain of painful swallowing, difficulty in swallowing, weak cough, and inability to turn the head. Prevention and treatment of infection after inhalation injury, due to airway and lung damage, cilia function destruction, airway secretions and foreign bodies can not be discharged in a timely manner, local and systemic resistance decline, etc., often lead to airway and lung infections. Once the infection, if not treated in time, it can be complicated by acute respiratory failure and become an important focal point of systemic infection and induce sepsis. So, what are the methods of prevention of injury above the vocal cords? The following is a brief introduction: The disease is caused by traumatic factors, no special preventive measures, should pay attention to life safety on weekdays, avoid trauma. Thorough removal of foreign bodies and shed necrotic mucosal tissue in the airway and unobstructed drainage are the basic measures to prevent and treat infection, followed by strict aseptic technique and sterilization isolation, strict control of trauma-lung-trauma bacterial cross-infection; regular smear and culture of airway secretions, and selection of sensitive antibiotics. In addition, systemic supportive therapy should be strengthened to improve the immune function of the body, which is important for the prevention and treatment of infection.
