Panfacial Trauma- A Case Report
Abstract: The majority of panfacial fractures are accompanied by concurrent organ damage. Panfacial fracture management is difficult and necessitates careful planning, sequencing, and sufficient understanding of the anatomy and management of the condition. In any trauma situation, the ABCDEs (airway, breathing, circulation, disability, and exposure) always remain the primary care priorities. Maxillofacial surgeons are essential in the early stabilization of fractures, the management of localized bleeding into the face, and the …
