Abstract
Among head injuries, frontobasal fractures play an important role due to frequently concomitant intracranial complications. Intracranial hematomas, cerebral contusions, depressed fractures, and intracranial air were readily detected by computed tomography (CT). Traumatization of intraorbital structures often associated with blowout fractures and herniation of cerebral parenchyma into the ethmoidal, frontal, or sphenoidal sinuses were best demonstrated by CT. In assessing soft tissue structures, CT was superior to multidirectional tomography, which tended to be more suitable for fine detail study of bony structures. CT was helpful for diagnosing inflammatory processes due to bacterial invasion not infrequently following traumatic communication between the paranasal sinuses and the cranial cavity. Sequelae of head trauma such as posttraumatic porencephaly were clearly demonstrated by CT.
