In this communication, an extension of the retrolabyrinthine approach that has permitted safe, effective access to the petrous tip and clivus is presented. The basic technique involved complete mastoidectomy, preservation of the middle and inner ear structures, removal of the sigmoid and middle fossa plates, middle and posterior fossa craniotomies, ligation of the superior petrosal sinus, and division of the tentorium. Nine cases that exemplified the versatility of this approach constituted the basis of this paper: 2 cholesteatomas, 2 basilar artery aneurysms, 2 chordomas, and 3 meningiomas. The indications for, and complications of, this method have been discussed.
在本报告中，介绍了一种扩大的迷路后入路，该入路可安全、有效地到达岩尖和斜坡。基本技术包括全乳突切除术、保留中耳和内耳结构、切除乙状窦和中颅窝板、中颅窝和后颅窝开颅术、结扎岩上窦以及切开小脑幕。9例体现该入路多功能性的病例构成了本文的基础：2例胆脂瘤、2例基底动脉动脉瘤、2例脊索瘤和3例脑膜瘤。本文还讨论了该方法的适应证和并发症。
