Temporal bone fractures are mostly due to high-energy head trauma with high rates of concurrent intracranial and cervical spine injuries and belong to the wider spectrum of lateral skull base trauma. Given that the temporal bone represents the most complex bone structure in the human body, containing a multitude of vital neurovascular structures, variable clinical presentations may arise from such fractures, ranging from asymptomatic courses to serious consequences, such as conductive and/or sensorineural hearing loss, vascular and/or cranial nerve injury as well as cerebrospinal fluid leakage. The present paper presents typical clinical sequelae and provides a detailed illustration of characteristic imaging findings related to temporal bone injury. Last but not least, in the final section of the manuscript the focus is placed on distinct anatomic structures which may mimic fracture lines and, thus, entail a high potential for misclassification as temporal bone fractures.
颞骨骨折大多由高能头部外伤引起,常并发颅内和颈椎损伤,属于更广泛的侧颅底外伤范畴。鉴于颞骨是人体最复杂的骨骼结构,包含众多重要的神经血管结构,此类骨折可能会出现多种临床表现,从无症状到严重后果,如传导性和/或感音神经性听力损失、血管和/或脑神经损伤以及脑脊液漏。本文介绍了典型的临床后遗症,并详细阐述了与颞骨损伤相关的特征性影像学表现。最后但同样重要的是,在本文的最后部分,重点关注了可能模仿骨折线的不同解剖结构,因此极有可能被误分类为颞骨骨折。
