颅底术后骨质缺损的钛网重建

目的探讨钛网在颅底重建中的可行性和外科技术。方法回顾性分析2002年11月至2004年11月采用钛网修复的11例颅底缺损患者的临床资料及随访结果。结果11例患者中颅底肿瘤6例，颅底骨纤维异常增生症3例，脑膜脑膨出2例。手术人路：经颅面联合入路手术7例，经额入路及扩大经额入路3例，经面中部掀翻入路1例。修补中、侧颅底2例，前、中颅底及蝶鞍6例，前颅底及眶板3例。术后短期内3例患者有少量无症状性颅内积气，未经治疗而自愈；1例患者发生短暂性脑脊液鼻漏，局部明胶海绵填塞及碘纺纱条压迫后自愈。术后平均随访14．4个月，无钛网移位和颅内感染等并发症。结论钛网用于颅底大型骨质缺损修复是安全的、可行的。

Using of titanium mesh for the reconstruction of skull base defect

Objective The purpose of this study is to evaluate the possibility and surgical principle of titanium mesh used for the reconstruction of skull base bone defect. Methods The clinical data of 11 patients with defect of skull base bone repaired with titanium mesh were retrospectively analysed. Results Among 11 patients, there were 6 patients with skull base tumor, 3 patients with fibrosis hyperplasia, 2 patients with encephalomeningocele. The surgical approach included craniofacial approach in 7 patients, transfrontal and extended transfrontal approach in 3 patients, trans-midface approach in 1 patient. The anterior and lateral skull base was repaired in 2 patients, anterior and middle skull base and sellar repaired in 6 patients, anterior skull base and orbital floor repaired in 3 patients. In early postoperative period, there were 3 patients with intracranial pneumatosis, but without symptom, and 1 patient with transient cerebrospinal leakage. Following-up for average 14. 4 months, there was no titanium mesh displacement and intracranial infection in all patients. Conclusions The titanium mesh used for the repair of skull base bone defect was both possible and safe.
