Maxillofacial injuries are among those most frequently sustained by military personnel. The air evacuation of patients with facial trauma is, therefore, an important aspect of military aviation medicine and one requiring special consideration. In the latter part of World War II this type of casualty received top priority in the selection of patients for air evacuation.1 Advancements in the concept of aerial transportation of maxillofacial injuries have evolved from extensive research on motion sickness, mechanical phases of air transportation, and physiological factors in flight. Experiences during World War II and the Korean conflict have demonstrated the value of the following three important measures in the air evacuation of facial trauma cases2-7: (1) early temporary stabilization; (2) control of motion sickness, and (3) quick release mechanisms of jaw fixation.
Early temporary stabilization of maxillofacial injuries facilitates the procedures incident to evacuation of the patient for definitive treatment, so that
