Hemi Le Fort III Fracture with Subdural and Subarachnoid Pneumocephalus with a Mild Mount Fuji Sign

subdural and ABSTRACT: Extensive fractures in the fixed facial skeleton combined with traumatic brain injury can cause functional and esthetic impairments, possibly threatening the patient’s life. Male patient, 50-year-old, victim of physical aggression, presented with persistent headache and dizziness, fractures in the naso-orbito-ethmoidal, zygomatic-maxillary and right pterygoid process regions, among other minor patterns of facial fracture, with mobility to maxillary traction of the third midface unilaterally. Clinical-imaging findings revealed a Hemi Le Fort III fracture and subdural and subarachnoid pneumocephalus with a mild Mount Fuji Sign. The proposed treatment was facial osteosynthesis and conservative intravenous drug treatment of the pneumocephalus. The patient had a good recovery, with no postoperative motor or functional deficits. The correct management of the patient with facial trauma associated with craniotrauma offers benefits, restoring stability of facial architecture and preventing or correcting neurosurgical complications.
