Abstract：Objective To investigate the clinical efficacy of retractorless surgery for anterior circulation aneurysms via transorbital keyhole approach.Methods The clinical data of 51 patients with anterior circulation aneurysm undergoing a minimally invasive surgery via the transorbital keyhole approach were analyzed retrospectively.The operation was performed using the retractorless technique (retractorless group) in 27 cases and fixed retractor in 24 (control group).The intraoperative conditions,brain retraction injury evaluated by postoperative CT and MRI within 7 days,and the results of Activities of Daily Living Scale (ADL) and modified Rankin Scale (mRS) 1 month after the operation were compared between two groups.Results The operation time,intraoperative blood loss and aneurysm rupture showed no statistical difference between the two groups (P＞ 0.05).However,the incidence of brain retraction injury was significantly different between the two groups (P=0.042).Compared with control group,The ADL and mRS of retractorless group was better those of the control 1 month after the operation (P=0.017,0.033 respectively).Conclusions The retractorless technique used in the operation via transorbital keyhole approach for anterior circulation aneurysm can replace the fixed retraction.Compared with the retractor surgery,retractorless surgery does not increase operation time,intraoperative blood loss and rate of aneurysm rupture,and is helpful in reducing brain retraction injury,protecting neurological function and improving patients' postoperative quality of life.
