Objective To summarize the experiences of microsurgical management in 64 cases with large acoustic neuromas. The feasibility of facial nerve preservation and possibility of acoustic nerve preservation were evaluated. Method The unilateral suboccipital approach were used in 59 cases and transpetrosal approach were used in 5 cases in which the tumor had involved petroclival area. Result The tumors were totally removed in 56 cases (88%), subtotally removed in 7 cases and partially removed in 1 case. The anatomical...

Objective To summarize the experiences of microsurgical management in 64 cases with large acoustic neuromas. The feasibility of facial nerve preservation and possibility of acoustic nerve preservation were evaluated. Method The unilateral suboccipital approach were used in 59 cases and transpetrosal approach were used in 5 cases in which the tumor had involved petroclival area. Result The tumors were totally removed in 56 cases (88%), subtotally removed in 7 cases and partially removed in 1 case. The anatomical facial nerve reservation had been acchieved in 57 cases (89%) and functional reservation (Ⅰ -Ⅲ grade) in 43 cases (67%). In 22 patients who had hearing function preoperatively, 6 cases (27%) preserved their hearing function after surgery. One patient (1.5%) died postoperatively. Conclusion Most of large acoustic neuromas can be totally removed in one stage by using microsurgical skill and it's possible to preserve the facial and acoustic nerves although it is very difficult to preserve the hearing function. The importance of protecting ventrolateral veniplex of pons and anterior inferior cerebellar artery are emphasized during surgical management.

目的总结 64例大型听神经瘤显微外科手术的体会,探讨面、听神经功能保留的可能性和可行性。方法59例采用单侧枕下入路,5例巨大型累及岩尖斜坡者采用经岩入路,所有病例均采用显微外科技术行肿瘤切除术。结果肿瘤全切除56例(88%),次全切除7例,大部切除1例。面神经解剖保留57例(89%),功能保留43例(67%)。术前尚有听力者22例,术后听力保存者6例(27%)手术,死亡1例(1.5%)。结论大部分大型听神经瘤采用显微外科技术可行1期全切除和面神经的保留,强调保护桥脑腹外侧静脉丛和小脑前下动脉的重要性。对大型听神经瘤亦应争取面神经和听力的保留。

Objective To provide the anatomic data for the operations through retrosigmoid approach. Methods 20 adult skull specimens were observed to define the location and region of bony window in the operations by gross anatomical method. Simulated operations were performed On 15 dry adult head specimens and the structures of cerebellopontine angle were exposed, then the distances from the bony window to trigeminal nerve, facial nerve, vestibulocochlear nerve, glossopharyngeal nerve and anterior inferior cerebellar...

Objective To provide the anatomic data for the operations through retrosigmoid approach. Methods 20 adult skull specimens were observed to define the location and region of bony window in the operations by gross anatomical method. Simulated operations were performed On 15 dry adult head specimens and the structures of cerebellopontine angle were exposed, then the distances from the bony window to trigeminal nerve, facial nerve, vestibulocochlear nerve, glossopharyngeal nerve and anterior inferior cerebellar artery loop were measured by gross anatomica method. Results The bony window, which does not overlap with sigmoid sinus, was a circle with a radius of 20mm, whose center located behind the midpoint of the line from parietal notch to mastoid apex with a distance of 26.38±3.95mm. The distances between bony window and the spots of cerebral dura mater through which trigeminal nerve, facial nerve, vestibulocochlear nerve, glossopharyngeal nerve traversed, and the distance from bony mindow to anterior inferior cerebellar artery loop were 56.63±4.55mm, 47.23±3.69mm, 45.91±3.99mm,43,73± 4.01 mm, 45.95±3.77mm respectively. Conclusion The above method of locating bony window through retrosigmoid approach is ideal and feasible, the structures in cerebellopontine angle should be protected when the operations are being performed.

目的 为乙状窦后入路手术提供解剖学依据。方法 对 2 0个成人颅骨标本乙状窦后入路手术骨窗的确定、开窗范围的大小进行观测。 15个成人尸头乙状窦后入路开窗显露桥小脑三角区域的结构 ,测量骨窗至三叉神经、面神经、前庭蜗神经、舌咽神经和小脑下前动脉袢的距离。结果 顶切迹至乳突尖连线中点向后 2 6 38± 3 95mm作为骨窗的中点 ,以该点为圆心 ,画出半径为 2 0mm的圆 ,该圆形区域与乙状窦不重叠。骨窗至三叉神经、面神经、前庭神经、舌咽神经穿硬脑膜和小脑下前动脉袢处的距离分别为 5 6 6 3± 4 5 5mm、4 7 2 3± 3 6 9mm、4 5 91± 3 99mm、4 3 73± 4 0 1mm、4 5 95± 3 77mm。结论 顶切迹至乳突尖连线中点向后2 6 38± 3 95mm处为乙状窦后入路手术开放骨窗的中点 ,骨窗的大小控制在半径为 2 0mm的圆形区内较为理想 ,手术中应注意保护桥小脑三角区域的有关结构。

Objective: To investigate systematically the microanatomy of the temporal bridging vein and its tributaries. Methords: On 10 adult cadaver brain specimens (20 hemispheres), the temporal bridging veins were studied under an operating microscopy, from the origins of their tributaries to their terminations. Results: Four venous configurations were found: venous lakes (tentorial sinuses) running in the tentorium before entering the sinuses 15%(3 sides), the candelabra of veins uniting to form one large draining...

Objective: To investigate systematically the microanatomy of the temporal bridging vein and its tributaries. Methords: On 10 adult cadaver brain specimens (20 hemispheres), the temporal bridging veins were studied under an operating microscopy, from the origins of their tributaries to their terminations. Results: Four venous configurations were found: venous lakes (tentorial sinuses) running in the tentorium before entering the sinuses 15%(3 sides), the candelabra of veins uniting to form one large draining vein 40%(8 sides), single independent draining vein 20%(4 sides) and multiple independent draining veins 25%(5 sides). 107 tributaries and 43 terminations of the temporal bridging veins were found in our specimens .The locations of the terminations of the bridging veins were divided into three groups : the transverse sinus group 54%(23), the tentorial group 23%(10) and the petrosal group 23%(10). Conclusions: Knowledge of this venous anatomy can protect bridging veins well in the operation with less venous complications.

目的:系统了解颞叶桥静脉及其属支的显微解剖。方法:在手术显微镜下观察10例20侧成人头部标本的颞叶桥静脉,由各属支起源追踪至静脉汇入点,测量有关数据。结果:颞叶桥静脉有4型:Ⅰ静脉湖型15%(3侧),Ⅱ烛台型40%(8侧),Ⅲ单干型20%(4侧),Ⅳ多干型25%(5侧)。20侧半球共有107条桥静脉属支、43个静脉汇入点,静脉汇入点分布于横窦区54%(23个)、小脑幕区23%(10个)、颞骨岩部区23%(10个)。结论:熟悉颞叶桥静脉的显微解剖,是在相关手术中保护桥静脉的基础。
