| 摘 要： | 目的研究扩大乙状窦后入路对桥小脑角区病变手术暴露的改善情况。方法在10例(20侧)成人湿性尸头上模拟枕下乙状窦后入路,进一步显露横窦、乙状窦,模拟扩大乙状窦后入路,分别以内听道口、三叉神经腔口(Meckel腔口)、斜坡中点为参照点,测量其在两种入路中与骨窗上下缘、内外侧缘所成最大角度及距离,并观察扩大乙状窦后入路对桥小脑角区重要神经、血管结构的显露状况。结果扩大乙状窦后入路骨窗外侧缘中点到内听道口、Meckel腔口、斜坡中点的距离较枕下乙状窦后入路显著缩短(均P<0.05);骨窗上下缘、内外侧缘与参照点所成最大角度均扩大,具有统计学差异(均P<0.05)。结论扩大乙状窦后入路有利于增加手术暴露范围、扩大手术视角,提高桥小脑角区大型肿瘤的全切除率以及保护重要的神经、血管。

| Abstract: | Objective To investigate the improvement of surgical field exposure in cerebellopontine angle area via the extended retrosigmoid approach.Methods Suboccipital retrosigmoid approach was used on 10 adult fresh cadaveric heads(20 sides) and then the extended retrosigmoid approach was simulated by further revealing the transverse sinus and sigmoid sinus.Using internal auditory meatus,the entrance of Meckel's cave and midpoint of the clivus as reference points respectively,the maximum angles and distances betwee... |
