The authors report their experience in the surgical management of small (less than 1.5 cm diameter) acoustic neuromas. Twenty-nine patients were treated. They had suffered symptoms of unilateral eighth nerve dysfunction on average for 37 months. High resolution CT with iv contrast was the primary investigation. In equivocal cases, air meatography was performed. All operations were performed by the senior author (LS). All tumours were totally removed, there were no deaths and all patients had an excellent result. There were 6 complications (CSF leak 3; meningitis 2; deep venous thrombosis 1). The facial nerve was preserved in 26 cases (and functioned adequately in all) and the cochlear nerve in 62%. In 4 cases with hearing pre-operatively, the decibel loss was the same or less post operatively. In 8 cases speech discrimination remained above 35%.
作者报告了他们在手术治疗小型（直径小于1.5厘米）听神经瘤方面的经验。共治疗了29例患者。他们平均有37个月的单侧第八神经功能障碍症状。主要检查方法是静脉注射造影剂的高分辨率CT。在诊断不明确的病例中，进行了气脑造影。所有手术均由资深作者（LS）完成。所有肿瘤均被完全切除，无死亡病例，所有患者预后良好。有6例并发症（脑脊液漏3例；脑膜炎2例；深静脉血栓形成1例）。26例患者的面神经得以保留（且全部功能良好），保留蜗神经的比例为62%。术前有听力的4例患者，术后分贝损失相同或更小。8例患者的言语辨别率保持在35%以上。
