Abstract:Objective To investigate the application value of artificial dura mater tension-reduced suture in two-stage cranioplasty for patients with severe closed craniocerebral injury.? Methods A retrospective was performed on the clinical data of 173 patients with severe closed craniocerebral injury. There were 92 patients treated with conventional dural-cut decompression ( control group) and 81 patients treated with artificial dura tension-reduced suture(treatment group). Three months later, all patients underwent cranioplasty in that operation time, intraoperative arachnoid damage and early postoperative complications were observed and compared between two groups.? Results The incidence of arachnoid damage (3.7% vs 30.4%)and the operation time［(85.60±13.08)min vs(95.53±26.39)min] were significantly lower in treatment group than those in control group (all P<0.05). During 14 days after operation, the incidence rates of subcutaneous blood and effusion accumulation (3.7% vs 27.2%) and epilepsy (3.7% vs 12.0%) in treatment group were statistically lower than those in control group (P<0.05, P<0.01).? Conclusion The artificial dura mater tension-reduced suture has a certain value in reducing the occurrence of early postoperative complications in two-stage cranioplasty.
