Leakage of CSF remains a frequent complication of acoustic neuroma surgery in contrast with the significant reductions achieved in mortality and morbidity. The rate of CSF leakage following acoustic neuroma excision is presented for 49 consecutive patients. The first 23 operations were performed before the introduction of a new technique for sealing off air cells in the internal auditory meatus and the following 26 with this new method. CSF leakage occurred in nine of the first 23 patients compared with one of 26 patients using this method (p < 0.01). The two groups were similar for tumour size and facial nerve preservation rate. The technique, which avoids the need for a second donor site wound or continuous lumbar drainage, is described and factors leading to CSF leakage are discussed.
与死亡率和发病率的显著降低形成对比的是，脑脊液漏仍是听神经瘤手术常见的并发症。本文报告了连续49例听神经瘤切除术后脑脊液漏的发生率。前23例手术是在内耳道气房封闭新技术应用之前进行的，后26例采用了这种新方法。前23例患者中有9例发生脑脊液漏，而采用这种方法的26例患者中只有1例发生脑脊液漏（p<0.01）。两组在肿瘤大小和面神经保留率方面相似。本文描述了这种无需第二个供体部位伤口或持续腰椎引流的技术，并讨论了导致脑脊液漏的因素。
