桥小脑角肿瘤的显微手术

Microsurgical treatment for tumors of cerebellopontine angle

目的采用显微外科技术切除桥小脑角肿瘤,重点分析微创手术技巧。方法回顾性总结32例采用显微外科技术切除桥小脑角肿瘤的经验。结果全部均经枕下乳突后曲棍球杆形切口,小骨窗入路,全切除26例,次全切除5例,部分切除1例,术后轻度面瘫7例。结论采用微创显微外科技术选择最佳手术入路,能够达到肿瘤全切除保护神经功能之目的。

[Objective] To explore the surgical skill in the resection of tumor on cerebellopontine angle by microsurgical technique. [Method] To summarize the surgical skill in the resection of tumor on cerebellopontine angle by microsurgical technique retrospectively. [Results] Microsurgery all entered from ossicle window through post-mastoid under pulvinar, showing hockey incisions. Total, subtotal and partial resection of tumor were undertaken in 26, 5 and 1 patients respectively, with 6 cases suffered from shght facial paralysis after surgery. [Conclusion] The best operative approach selected by microsurgery can protect the nerve in the total resection of brain tumor.
