目的:分析枕下乙状窦后入路切除听神经瘤术后常见并发症及相关因素。方法:对36例听神经瘤患者术后出现的并发症进行回顾性分析。结果:36例听神经瘤全切除28例,次全切除8例。术后出现听力丧失31例,面神经功能障碍18例,后组颅神经损伤4例,脑脊液漏3例,出现脑积水或原有脑积水加重2例,颅内感染1例,颅内出血1例,死亡1例。结论:听神经瘤术后听力丧失和面神经功能障碍发生率高,并发症的发生率与肿瘤的大小、囊性变及术者显微手术熟练程度相关。
OBJECTIVE: To analyze common postoperative complication and related factors in the treatment of acoustic neuroma after suboccipital sigmoid sinus posterior approach. Methods: A retrospective analysis was performed on the postoperative complications in 36 patients with acoustic neuroma. Results: There were 28 cases of acoustic neuroma in 36 cases and 8 cases of subtotal resection. There were 31 cases of hearing loss, 18 cases of facial nerve dysfunction, 4 cases of cranial nerve injury in the latter group, 3 cases of cerebrospinal fluid leakage, 2 cases of hydrocephalus or exacerbation of original hydrocephalus, 1 case of intracranial infection, 1 case of intracranial hemorrhage Case, 1 patient died. Conclusion: The incidence of hearing loss and facial nerve dysfunction after acoustic neuroma is high. The incidence of complications is related to tumor size, cystic degeneration and the degree of microsurgical skill.
