The present study aims to explore the effectiveness of decompressive craniectomy with bifrontal coronal incision in the management of severe contusion and laceration of bilateral fronto-temporal lobes, as well as the outcomes of early cranioplasty. The authors performed the bifrontal decompressive craniectomy on 56 patients with contusion and laceration of bilateral frontal and temporal lobes, and their follow-up treatment outcomes were tracked within 6 months using Glasgow Outcome Scale. The results showed that 33 patients (out of 56, 58.9%) have recovered, 12 patients (out of 56, 21.4%) have moderate defects, 5 patients (out of 56, 8.9%) have severe defects, 3 patients (out of 56, 5.3%) stayed in persistent vegetative status, and the remaining 3 patients (out of 56, 5.3%) have been dead. There was no persistent temporal hollowing. No patients required revision surgery with modified titanium mesh in this study. Particularly, 28 patients have successfully accepted the early cranioplasty with bone flap or computer-assisted design titanium mesh, and showed good recovery. These results together indicated that the decompressive craniectomy with bifrontal coronal incision in the management of severe contusion and laceration of bilateral fronto-temporal lobes can significantly relieve the comorbidity of intracranial hypertension, and improve the prognosis obviously, thus finally increasing the probability of successful rescue and decreasing the probability of mortality and disability.
