Tracheotomy is mainly a procedure to form artificial ventilation by cutting the cervical trachea and placing a plastic or metal catheter to connect it with other catheters, which is mainly applied to laryngogenic dyspnea, laryngeal edema and dyspnea caused by tumor compression. If a patient with cranial trauma has more sputum in the airway, which is more difficult to clear and requires prolonged ventilation, the patient can clear the airway and keep breathing through tracheotomy, and after the condition improves, the trachea can be removed and the wound can be sutured.
