在耳科学领域内,从临床检查和手术进路方面比较,再无比岩尖部病损更难捉摸的部位。颞骨侵蚀的特点是晚期才出现症征,它与内耳道或桥小脑角相比,当后者病变仅数毫米时即可引起症状,而大块岩尖破坏初期却可无症状。不管是感染或肿物,骨迷路对溶骨性损害均有明显的抵抗力,故症状出现便意味着颞骨或其邻近结构的神经-血管被侵,但开始时很少是具有局部定位意义的体征,因而易于延误诊断。岩尖部病变包括囊肿、感染、肿瘤及血管性损害等,其早期症状往往无何特点,如由于脑膜
In the field of otology, there are no more elusive sites than the petrous apex lesions in terms of clinical examination and surgical approaches. Radial erosion is characterized by late signs of symptoms. Compared with the inner ear canal or cerebellopontine angle, the latter can cause symptoms when the latter lesion is only a few millimeters, but the initial destruction of large rock can be asymptomatic. Whether it is an infection or a tumor, the bone labyrinth has obvious resistance to osteolytic lesions. Therefore, the appearance of symptoms means that the nerve-vessels of the sacrum or its adjacent structures are invaded, but it is rarely localized at the beginning. Signs, thus making it easy to delay diagnosis. The petrous apex lesions include cysts, infections, tumors, and vascular lesions, and their early symptoms often have no characteristics, such as due to the meninges.
