Abstract： 目的探讨伽玛刀治疗对三叉神经鞘瘤的临床疗效.方法回顾性分析1994年12月至2003年12月于本中心行伽玛刀治疗并随访的58例三叉神经鞘瘤,肿瘤平均体积4.6cm3,平均周边剂量13.1Gy,平均中心剂量28.3Gy.结果平均随访期42.5个月,影像随访证实4例肿瘤基本消失,34例明显萎缩,16例体积变化不明显,4例体积增大,肿瘤总控制率93%.28例患者的临床症状明显改善,23例临床症状无变化,7例临床症状持续加重.13例伴有继发性三叉神经痛的患者中,10例伽玛刀治疗后明显缓解或消失.结论伽玛刀治疗对中小型三叉神经鞘瘤安全有效,并可有效地改善其临床症状,保护瘤周颅神经的功能.
