<unk>  (TBI) is damage to the<unk>  tree (the structure of airways involving the trachea and bronchi). It can result from blunt or penetrating neck or chest trauma. The airways may also be injured by inhaling harmful fumes, or aspirating liquids or objects.
Though rare, TBI is potentially fatal. TBI can cause the airway to be blocked and can restrict breathing. Other injuries accompany TBI in about half of cases. Most people with the injury who die do so before receiving emergency care, due to other injuries to vital organs, profuse bleeding, and insufficient airway. Of those who do reach a hospital, the mortality rate is about 30%.
Early diagnosis is important to prevent complications, which include narrowing of the airway, respiratory infections, and damage to the lung tissue. Diagnosis involves bronchoscopy to visualize the airways, and X-ray can be used as well.  Signs and symptoms include difficulty breathing, hoarseness, coughing, and abnormal breath sounds; however they vary based on the location and severity of the injury.  In the emergency setting, intubation with an endotracheal tube can be used to ensure that the airway remains open so the patient can breathe.   Surgery to repair a<unk>  tear is usually considered standard; however in less severe cases TBI may be managed conservatively and allowed to heal without surgery.
