目的介绍一种新的、改良的乙状窦前入路的开颅方法。方法对124例岩斜区肿瘤,通过颞枕小脑幕上下双骨瓣开颅、改良乙状窦前入路手术方式,探讨传统乙状窦前入路和改良乙状窦前入路的优缺点。结果124例改良乙状窦前入路,手术中无静脉窦破裂出血的发生,术后无颅骨缺损、局部积液的发生。手术操作安全、简便、易于掌握。结论改良乙状窦前入路在传统入路基础上,通过对开颅骨瓣的改良,避免了手术中静脉窦损伤、手术后颅骨达到完全解剖复位,不仅使局部美观,还有效地降低了术后并发症的发生。
Objective To introduce a new and improved method of craniotomy of the sigmoid anterior approach. Methods 124 cases of petroclival tumors, through the temporal roof of the occipital tentorrotraplex craniotomy, modified sigmoid anterior approach to discuss the traditional sigmoid anterior approach and modified sigmoid anterior approach advantages and disadvantages . Results 124 cases of modified sigmoid anterior approach, surgery without venous sinus bleeding occurred, no skull defects, local effusion occurred. Surgical operation is safe, easy and easy to grasp. Conclusion The improved sigmoid anterior approach is based on the traditional approach, through the improvement of the cranial bone flap, to avoid the operation of the sinus venous sinus surgery to achieve a complete anatomic reduction of the skull, not only the local aesthetic, but also effectively reduce the operation After the occurrence of complications.
