The importance of preserving the superior petrosal vein has received increasing attention in the surgical treatment of pathologies involving the petrous apex. Recent reports have associated postoperative auditory nerve dysfunction with petrosal vein sacrifice. However, there is no systematic clinical study available thus far focusing on the postoperative auditory function after petrosal vein obliteration.
In 55 patients with meningiomas involving the petrous apex, pre- and intraoperative findings including petrosal vein sectioning were analyzed retrospectively concerning their impact on postoperative auditory function.
The petrosal vein was preserved in 26 (47%) cases. In 27 (49%) cases, this vein was not preserved. Hearing loss occurred in 11% of all cases. In the preserved-vein group, postoperative hearing loss occurred in 3 of 26 (11%) cases and in the sacrificed-vein group in 3 of 27 (11%) cases.
Sacrifice of the petrosal vein during surgery of petrous apex meningiomas seems not to have an impact on postoperative auditory function.
在涉及岩尖的病变手术治疗中，保留岩上静脉的重要性已受到越来越多的关注。近期报告将术后听神经功能障碍与牺牲岩上静脉相关联。然而，迄今为止尚无系统的临床研究聚焦于岩上静脉闭塞后的术后听觉功能。
对55例累及岩尖的脑膜瘤患者，回顾性分析术前及术中包括岩上静脉切断在内的各项发现对术后听觉功能的影响。
26例（47%）保留了岩上静脉。27例（49%）未保留该静脉。所有病例中听力损失发生率为11%。在保留静脉组，26例中有3例（11%）术后出现听力损失；在牺牲静脉组，27例中有3例（11%）术后出现听力损失。
在岩尖脑膜瘤手术中牺牲岩上静脉似乎对术后听觉功能无影响。
