Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Blunt trauma to the frontal bone may result in a depressed frontal sinus fracture. Often, there is an associated laceration. Isolated frontal fractures normally do not have the associated features of massive blunt facial trauma such as seen in LeFort II and III fractures. Careful nasal speculum examination may reveal blood or CSF leak high in the nasal cavity. Posterior table involvement can lead to mucopyocele or epidural empyema as late sequelae. Involvement of the posterior wall of the frontal sinus may occur and result in intracranial injury or dural tear. Frontal fractures may be part of a complex of facial fractures, as seen in frontonasoethmoid fractures, but generally more extensive facial trauma is required.
