目的探讨改良前颞下入路手术切除岩斜区及海绵窦区肿瘤的方法及疗效。方法回顾性分析15例岩斜区及海绵窦区肿瘤的临床资料,均采用改良前颞下入路手术切除肿瘤。结果肿瘤全切除10例,近全切除3例,大部分切除2例。术后发生动眼神经麻痹2例、面瘫1例、偏瘫1例,无脑脊液漏、颅内感染、死亡病例。出院后随访3个月至2年,平均1.1年,未发现肿瘤复发。结论改良前颞下入路创伤小,操作相对简单,对海绵窦、中上斜坡区域暴露充分,适合这一区域肿瘤的手术治疗。
Objective To explore the method and efficacy of modified anterior inferior temporal approach for removal of petroclival and cavernous sinus tumors. Methods The clinical data of 15 patients with petroclival and cavernous sinus tumors were analyzed retrospectively. All patients underwent anterior anterior inferior temporal approach for resection of the tumor. Results Total tumor resection in 10 cases, nearly total resection in 3 cases, most resection in 2 cases. Oculomotor nerve paralysis occurred in 2 cases, 1 case of facial paralysis, hemiplegia in 1 case, no cerebrospinal fluid leakage, intracranial infection and death. After discharge from hospital for 3 months to 2 years, with an average of 1.1 years, no tumor recurrence was found. Conclusion The improved anterior inferior temporal approach has the advantages of less trauma and relatively simple operation. It is well exposed to the cavernous sinus and middle-upper slope area and is suitable for the surgical treatment of tumors in this area.
