Intradural tumours affecting the clivus may be divided into three categories depending the area primarily involved by tumour. The second area extends from the spheno-occipital synchondrosis to the level of the jugular foramina. This area is best approached through the petrosal approach and suited for patients with serviceable hearing on the side of the lesion. 35 cases having skull base lesions were operated by the Skull Base Surgery Group of Ege University Medical Faculty between October 1993 and December 1997. 8 out of 35 cases having the intradural tumours affecting the petroclival and anterior cerebellopontine region, the petrosal presigmoid approach was performed in 4 patients. As hearing was absent in another 4 patients, the translabyrinthine route was coupled a the petrosal craniotomy (transtemporal approach). The aim of this article is to highlight the definitions, indications, hints and pitfalls of the approach from the otoneurological point of view.
根据肿瘤主要累及的区域，影响斜坡的硬膜内肿瘤可分为三类。第二个区域从蝶枕软骨结合延伸至颈静脉孔水平。该区域最佳的手术入路是经岩骨入路，适用于病变侧听力尚好的患者。1993年10月至1997年12月期间，伊兹密尔埃杰大学医学院颅底外科组对35例颅底病变患者进行了手术。在35例硬膜内肿瘤累及岩斜区和小脑脑桥前区的病例中，4例患者采用了经岩骨乙状窦前入路。另外4例患者因听力丧失，采用经迷路入路联合经岩骨开颅术（经颞入路）。本文旨在从耳神经学角度强调该入路的定义、适应证、要点及陷阱。
