Abstract: Objective To explore the operation time and application value of intracranial pressure monitoring in treatment of patients with bifrontal lobe of brain contusion and laceration.Methods Clinical data of 66 patients with bifrontal lobe of brain contusion and laceration from 2005 to 2010 were studied retrospectively.66 patients were underwent bifrontal decompressive craniectomy.35 cases treated by bifrontal decompressive craniectomy combined with intracranialpressure monitoring were included in monitoring group.31 cases treated only by bifrontal decompressive craniectomy were included in control group.The clinical efficacy of both two groups were compared 12 months later.The data were retrospectively analyzed in order to summary the clinical characteristics,operational time,application value of intracranial pressure monitoring and prognosis.Results 8 cases got emergence operation,58 cases were operated during the medical treatment because their situation developed worse gradually.All of the patients were followed up for twelve months.According to GOS assessment,there are 3 cases died,1 case with persistent vegetative state,2 cases with severe disability,4 cases with moderate disability,25 cases got good recovery in monitoring group.There are 5 cases of dearh,2 case with persistent vegetative state,2 cases with severe disability,6 cases with moderate disability,16 cases got good recovery in control group.The favorable prognosis rate of monitoring group and control group was 71.43% and 51.61%(P＜0.05).Conclusion The situation of many patients with bifrontal lobes brain contusion and laceration will become worse and worse gradually.The doctors should observe the patients carefully and operate on them in time.The bifrontal decompressive craniectomy is an effective method for the surgical management.The intracranial pressure monitoring can dynamically observe ICP,providing the objective and accurate evidence,and improve the prognosis of patients.
