Endoscopy-assisted cerebral falx incision via unilateral approach in treatment of dissymmetric bilateral frontal contusion.

摘要

Dissymmetric bilateral frontal contusion (DBFC) is relatively frequent in the clinic. In this study, we aimed to investigate the development tendency, clinical features, and treatment experience of DBFC and to summarize out experience in treating these patients via minimally invasive means-endoscopy.Over the past 3 years, we have treated a total of 31 patients with DBFC using endoscopy-assisted unilateral cerebral falx incision. We used a 30-degree endoscope to observe the involvement of brain contusion and whether the brain contusions have been cleaned thoroughly. Another 30 patients treated by routine bilateral approach within the same period were taken as controls.Seventeen cases (54.8%) in the unilateral-operation group survived and were in good condition, 8 cases (25.8%) had moderate disability, and 4 cases (12.9%) had severe disability; 1 case (3.2%) was in vegetable state, and 1 case (3.2%) died. Compared with the control group, the GOS score was not significantly different in the unilateral-operation group, but the operation time, blood transfusion volume, length of hospital stay, incidence of mental disorder, and incidence of olfactory nerve injury were greatly reduced in the unilateral-operation group.Endoscopy-assisted unilateral cerebral falx incision can shorten the operation time and reduce surgical trauma and complications when used for treatment of patients with DBFC.
