听神经瘤起源于听神经鞘又称听神经鞘瘤,是桥脑小脑角区最常见的良性肿瘤,即使多次复发亦不发生恶变。本瘤占颅内肿瘤的8％～12％,小脑桥脑角肿瘤的75％～95％。听神经瘤多数为单侧性。听神经瘤的治疗以手术为主,若能完全切除可得到根治。由于肿瘤与脑干紧密相连,其周围重要神经血管丰富,手术较为复杂。近年来诊断治疗技术的发展,听神经瘤的手术方法及效果也明显提高。现将听神经瘤 Acoustic neuroma originated in the auditory nerve sheath, also known as acoustic schwannoma, is the most common benign pontine cerebellum tumor area, even if multiple recurrence does not occur malignant. The tumor accounts for 8% to 12% of intracranial tumors, cerebellar pontine tumors of the brain 75% to 95%. Acoustic neuroma mostly unilateral. The treatment of acoustic neuroma surgery, if completely removed can be cured. As the tumor is closely connected with the brain stem, its peripheral neurovascular rich, the operation is more complicated. In recent years, the development of diagnostic techniques, acoustic neuroma surgery methods and the effect is also significantly improved. Now acoustic neuroma
