Traumatic acute brain herniation through the ear in a child: concealed compound fracture

ABSTRACT

A seven-year-old girl presented to Sultan Qaboos University Hospital, Oman, with a history of having been hit by a motor vehicle. After this, she had right-sided cerebrospinal fluid otorrhoea, and a week later, brain matter extruded through the right ear. A computed tomography scan of the brain demonstrated a tegmen fracture communicating with the external auditory canal. There was no hearing or facial nerve impairment and an otoscopic examination showed an intact tympanic membrane. She underwent a transcranial repair of the middle cranial fossa base, which revealed a wide dural and bony defect of the tegmen with herniation of the temporal lobe. Repair was made with an intradural patch of artificial dura. The rarity of this type of presentation of temporal bone fracture and its management are discussed
