The retrosigmoid approach is often used for posterior fossa pathology. Many variations of positioning exist. Here, we report a simple, safe, and quick positioning technique which maximizes patient safety, surgeon comfort, and intraoperative view.
We reviewed the senior author's prospective surgical database for retrosigmoid approaches to the posterior fossa and noted any complications or difficult exposures.
Over 970 retrosigmoid operations were performed over the course of 19 years. There were no positioning-related complications and no aborted surgeries due to inadequate exposure. No normal cerebellum was ever resected to increase exposure and no retractor was ever used in the posterior fossa.
Supine positioning for the retrosigmoid approach is an excellent and safe positioning alternative.
乙状窦后入路常用于后颅窝病变。存在多种体位变化。在此，我们报告一种简单、安全且快速的体位摆放技术，该技术可最大限度地提高患者安全性、术者舒适度及术中视野。
我们回顾了资深作者关于后颅窝乙状窦后入路的前瞻性手术数据库，并记录了任何并发症或暴露困难情况。
在19年的时间里共进行了970余例乙状窦后手术。没有与体位摆放相关的并发症，也没有因暴露不充分而导致手术中止的情况。从未为增加暴露而切除正常小脑组织，后颅窝也从未使用过牵开器。
乙状窦后入路采用仰卧位是一种极佳且安全的体位选择。
