摘要: 目的 :探讨前颅底区沟通性肿瘤的外科治疗方法和效果。 方法 :回顾性分析1997年1月至2006年12月60例前颅底区沟通性肿瘤患者的资料,均行外科治疗,经病理证实良性肿瘤21例,恶性肿瘤39例。手术入路的选择为颅面联合入路44例,眶内容物剜除术5例,鼻侧切开术3例,前额硬膜外入路5例,眶外侧入路3例。 结果 :肿瘤全切51例,次全切除4例,部分切除5例。肿瘤切除后前颅底区组织缺损的修复采用带蒂额肌帽状腱膜颅骨裂层瓣修复27例。术后45例临床症状有所改善,无手术死亡病例。并发症主要为颅神经损伤5例,伤口感染4例,其中局部加强换药愈合2例,清创缝合愈合2例,暂时性的脑脊液漏2例。术后放射治疗23例,剂量为45Gy~65Gy,术前或术后化疗15例,主要方案为DDP(顺铂)、5-FU(5-氟脲嘧啶)、平阳霉素。经信访或门诊随访1年~9年,死亡11例,失访2例。 结论 :前颅底区沟通性肿瘤以外科治疗为主,手术治疗是有效的,颅面联合入路是主要的手术方式,肿瘤切除后前颅底区组织缺损的修复采用带蒂额肌帽状腱膜颅骨裂层瓣修复是可靠和安全的。此区肿瘤的手术治疗难以达到肿瘤切除的"安全界",局部复发和远处转移是主要的死亡原因,需有计划地进行综合治疗,提高患者的生存率和生存质量。Abstract: Objective : To investigate the effect of surgical treatment on patients with anterior cranial base communi-cating tumor. Methods : We retrospectively analyzed the data from 60 patients with anterior cranial base com-municating tumors.All of the patients received surgical treatment.Pathological results showed 21 cases of be-nign tumors and 39 cases of malignant tumors.Forty-four patients underwent combined craniofacial ap-proach, five patients underwent evisceration of the eye, three patients received lateral rhinotomy, five patients underwent frontal epidural approach and three patients underwent orbital lateral approach. Results : Total tu-mor removal was achieved in 51 cases.Subtotal removal was achieved in four cases, and partial removal was achieved in five cases.The clinical symptoms were improved in 45 cases after surgery.The main compli-cations included cranial nerve injury in five cases, surgical wound infection in four cases (two cases were cured after intense local dressing replacement and two cases were cured after debridement), and temporal craniospinal fluid leakage in two cases.Twenty-three cases received postoperative radiotherapy (45Gy-65Gy).Fifteen patients received pre-or post-operative chemotherapy with DDP+5-Fu+pingyangmycin.The patients were followed up for 1-9 years.Eleven patients died during the follow-up period and two patients were lost to follow-up. Conclusion : The chief treatment for anterior cranial base communicating tumor is surgery and the most common procedure is the combined craniofacial approach.Local recurrence and distant metastasis are the primary causes of death.
