目的:探讨小型听神经瘤的早期诊断与显微手术治疗。方法:通过MRI平扫与增强及结合临床诊断小型听神经瘤9例,采用病侧枕下乙状窦后入路显微手术及内镜辅助切除肿瘤。认为MRI可用小型听神经瘤,乙状窦后入路显微手术较好的治疗方式。结果:术中全切100%,听力保留率75%,面神经保留率98%。结论:听神经瘤的早期诊断和术前肿瘤大小及听力水平是作为企图保存听力和面神经功能的主要决策。
Objective: To investigate the early diagnosis and microsurgical treatment of small acoustic neuroma. Methods: Nine patients with small acoustic neuroma diagnosed by plain scan and contrast enhancement combined with clinical diagnosis were treated with microsurgical and microscopic resection of the posterior submandibular sigmoid sinus. That MRI can be used small acoustic neuroma, sigmoid sinus posterior approach microsurgical better treatment. Results: 100% complete resection, hearing retention rate 75%, facial nerve retention rate of 98%. CONCLUSION: Early diagnosis of acoustic neuroma and preoperative tumor size and hearing level are the primary decisions in attempting to preserve hearing and facial nerve function.
