title: Control of cerebrospinal fluid otorrhea via C-arm-guided reduction of the zygomatic arch as a part of the temporal bone: interdisciplinary approach to an unusual craniomaxillofacial fracture.
abstract: Maxillofacial fractures are often associated with blunt head injuries, of which skull base trauma is a common component. However, most oral and maxillofacial surgeons do not provide definitive management of temporal bone fractures involving the skull base and their sequelae. Persistent cerebrospinal fluid (CSF) leakage that is refractory to conservative measures usually requires surgical closure to decrease the risk of meningitis. In general, reduction of the displaced fragment of the skull base in temporal bone fractures is not considered a priority. We describe an unusual case of craniomaxillofacial injury exhibiting CSF otorrhea because of a temporal bone fracture with a fragment that included the zygomatic arch. The persistent traumatic leakage was stopped after C-arm-guided reduction of the depressed zygomatic arch. This technique facilitated minimal and only necessary manipulation, without overcorrection, thereby avoiding additional damage to the surrounding tissues. The present case illustrates the definitive contribution of therapeutic measures based on maxillofacial surgery as part of an interdisciplinary approach to the management of the complications of severe head injuries; more invasive neurosurgery was thus avoided.
