The authors introduced a new approach for clipping of the incidental aneurysm of the middle cerebral artery (MCA) and reported the clinical results. We retrospectively reviewed 26 patients with 27 incidental MCA aneurysms who were treated from January 2010 to December 2012. All clippings were performed through a small temporal craniotomy and linear skin incision. Follow-up imaging showed complete occlusion of 26 aneurysms (96.3%), residual neck in one (3.7%). In one case, residual neck of the aneurysm did not grow on serial follow up. In one of 26 cases (3.8%), approach-related complication was retraction injury of the temporal cortex. Two patients developed postoperative infarction on the MCA territories due to vasospasm and on the cerebellum due to unknown causes. These were not approach-related complications. Operation time was 95 min-250 min (mean 143 min). There were no complications of temporal muscle atrophy, scar deformity, paresthesia, or pain around the scalp incision and frontalis palsy. This approach offers good surgical possibilities and little approach related morbidity in the clipping of incidental MCA aneurysms.
