本文报告了自1969至1991年间在卡罗林斯卡伽玛刀中心治疗的254例听神经瘤的经验，平均随访12个月，其中70%的病例早期CT或MRI表现为对比度丧失。单侧肿瘤缩小55%，无变化33%，增大12%。NF2肿瘤减少33%，无变化43%，增加24%。在17%的治疗后，面部出现了一定程度的虚弱，但总是随着后来功能的改善而改善。三叉神经病的发生率为19%。听力保留率为77%，伽玛刀治疗效果与显微手术相同，但无感染、出血或脑脊液漏的风险。它不需要住院治疗。病人可以在几天后重返工作岗位。因此，它应该作为每个听神经瘤患者的替代方案。
Presentation of the experiences with 254 acoustic neurinomas, treated at the Karolinska Gamma Knife Center from 1969 to 1991, with a minimum follow-up of 12 months.Early loss of contrast enhancement on CT or MRI was seen in 70%. Unilateral tumours showed size decrease in 55%, no change in 33%, and increase in 12%. NF 2 tumours had decrease in 33%, no change in 43%, and increase in 24%. Some degree of facial weakness was seen after 17% of treatments, but always with later improvement of function. The incidence of trigeminal neuropathy was 19%. Preservation of hearing was 77%.Gamma knife treatment is as efficient as microsurgery, but without risk of infection, bleeding or CSF leak. It requires no hospitalisation. The patient can go back to work after a few days. It therefore should be offered as an alternative to every acoustic neurinoma patient.
