Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Injury patterns of penetrating facial trauma can be predicted based on projectile type, entry location, and path. Midface injuries extend from the supraorbital rim superiorly to the oral commissure inferiorly and to the external auditory meatus posteriorly. Mandibular injuries extend from the oral commissure superiorly and to the lower border of the mandible inferiorly. Shotgun wounds typically involve both facial zones and will involve one or both eyes in 50% of patients. Fifty percent of patients with gunshot wounds (GSWs) to the mandible will require an emergency airway. Stab wounds are less likely to require emergency airway than GSWs. Additional structures that require consideration during the ED evaluation include brain, blood vessels, and esophagus.
