目的探讨后颅窝肿瘤开颅术中硬脑膜重建的临床价值。方法采用枕下正中或枕下正中向外的钩形切口;Y或H形切开硬脑膜后,用双极弱电流电凝硬脑膜边缘出血;术毕重建硬脑膜。结果28例后颅窝肿瘤全切术后仅1例发生局部积液,无脑脊液漏和无菌性脑膜炎等并发症发生;术后5d脑脊液检查基本正常;平均住院12d。结论后颅窝肿瘤开颅术中硬脑膜重建,恢复了相应的生理结构和功能,术后并发症少,缩短了术后恢复期。
Objective To investigate the clinical value of dural reconstruction in posterior fossa craniotomy. Methods The middle of the suboccipitum or the middle of the suboccipitum was cut out from the middle of the suboccipital cord. The dura mater was harvested by Y-shaped or H-shaped incision. Results In 28 cases of posterior fossa tumors, only one case had local effusion after operation, no complications such as cerebrospinal fluid leakage and aseptic meningitis occurred. The cerebrospinal fluid examination was basically normal on the 5th day after operation. The average hospitalization was 12 days. Conclusions The reconstruction of dura mater during craniotomy of cranial fossa tumors restored the corresponding physiological structure and function, reduced postoperative complications and shortened recovery period.
