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.
一名七岁女孩被送往阿曼的苏丹·卡布斯大学医院，她有被机动车撞击的病史。此后，她出现右侧脑脊液耳漏，一周后，脑组织从右耳挤出。脑部计算机断层扫描显示鼓室盖骨折并与外耳道相通。没有听力或面神经损伤，耳镜检查显示鼓膜完整。她接受了中颅窝底经颅修复术，术中发现鼓室盖有广泛的硬脑膜和骨缺损，颞叶疝出。使用人工硬脑膜硬膜内补片进行修复。本文讨论了这种颞骨骨折表现的罕见性及其治疗方法。
