Acute traumatic orbital encephalocele is a rare entity, with less than 25 cases reported. We hereby describe the first bilateral orbital encephalocele through a blow-in orbital fracture after a blunt cranial traumatism. Early treatment of the orbital traumatic encephalocele is necessary in order to avoid the increase of the intra orbital pressure that might damage the optic nerve. Repairing the orbital roof has to be performed in a rigid manner in order to avoid the transmission of the intracranial pressure variation to the orbit. In the present case, the reconstruction of orbital roof was performed using a subfrontal approach supported by a titanium mesh fixed with screws and a mixture of bone powder mixed and fibrin glue.
