摘要 目的初步研究伽玛刀治疗囊性听神经瘤的效果及并发症。方法我科从1997年到2010年应用OUR-旋转式伽玛刀治疗囊性听神经瘤共12例,其中男性7例,女性5例,年龄43~61岁,平均53岁。所有患者均未行手术或活检,临床及影像诊断为听神经瘤。肿瘤直径为3mm~4.2cm,所有患者无颅内高压,无明显脑积水;肿瘤部位在右侧者有7例,左侧者有5例,治疗周边剂量8~14Gy,等剂量曲线为50%。结果在随访期间,肿瘤缩小者有7例(87.5%),其中1例(12.5%)患者于治疗后6个月影像学显示肿瘤体积增大,考虑多系肿瘤坏死水肿所致,5年后随访提示缩小;肿瘤无增大者为1例。临床症状改善有6例,无变化有2例。结论在严格制适应证的前提下,伽玛刀治疗囊性听神经瘤疗效肯定,并发症少。
