Maxillofacial trauma refers to trauma to the oral cavity, cheeks, zygomatic forehead, etc. It is common in traffic accidents, accidents in life, work injuries and sports injuries, and with the development of transportation business traffic accidents cause more and more maxillofacial trauma. Since the maxillofacial area is close to the cranium, maxillofacial trauma is often accompanied by craniofacial injury. At the same time, bleeding or loose teeth after oral trauma may choke into the respiratory tract and cause breathing difficulties. For these reasons, special attention should be paid to the following points after maxillofacial trauma occurs. First of all, attention should be paid to whether the patient is asphyxiated. The causes of asphyxia can be divided into obstructive asphyxia and aspiration asphyxia. Obstruction of the larynx by foreign bodies, posterior tongue drop after mandibular fracture, tissue edema, etc. may occur when the air to become obstructed and endanger life. If the casualty is unconscious, blood, saliva, and vomit may be inhaled directly into the lungs to form inhalation asphyxia. In the absence of medical equipment, you can quickly use your fingers to remove the obstruction in the mouth or pull the tongue forward to relieve asphyxia. Next, attention should be paid to whether the patient is in shock or at risk of shock. In general, the proportion of shock after simple maxillofacial trauma is low, but if shock occurs and is not corrected promptly it can be life-threatening. If we observe pale, wet and cold skin, shallow and rapid breathing, accelerated heart rate, and indifference in the injured person, it means that the patient may be about to go into shock. At this point, the casualty should be sent to a nearby hospital for treatment as soon as possible. Finally, we should pay attention to the cranial injury of patients with maxillofacial trauma. Common craniocerebral injuries include concussion, old contusions, intracranial hemorrhage, skull or skull base fractures, etc. Common manifestations after craniocerebral injury include nausea and vomiting, coma, and clear fluid flow from the external nostril (cerebrospinal fluid fistula). Craniocerebral injury should be sent to a regular hospital as soon as possible, and treatment of craniocerebral injury takes priority over treatment of maxillofacial trauma.
