桥小脑角区(cerebellopontine angle,CPA)是颅内肿瘤好发部位,该区肿瘤一直是神经外科治疗难点之一。经乙状窦后入路因显露范围广泛,适合于各种大小的肿瘤,其全切率高,而为众多神经外科医师所采用。而近年来随着内镜、神经导航及神经电生理技术的应用,以及锁孔手术方式的发展,经乙状窦后入路已成为治疗该区肿瘤的理想手术方式之一。本文就目前经乙状窦后入路手术治疗桥小脑角区肿瘤的手术方式情况做一综述。
The cerebellopontine angle (CPA) is a predilection site for intracranial tumors, which has been one of the most difficult neurosurgical treatments. After the sigmoid sinus posterior approach due to reveal a wide range of suitable for various sizes of tumors, the high rate of full cut, and for many neurosurgeons used. In recent years, with the application of endoscopy, neuro-navigation and electrophysiological techniques, and the development of keyhole surgery, trans-sigmoid sinus posterior approach has become one of the ideal surgical approaches for the treatment of tumors in this area. In this paper, we reviewed the current surgical methods of transposition of the sigmoid sinus surgery in the treatment of cerebellopontine angle tumors.
