OBJECTIVE: To review our surgical experience in minimally invasive transcranial endoscope-assisted microsurgical treatment of @entity438 , using the supraorbital keyhole craniotomy. METHODS: The supraorbital keyhole approach was performed through an eyebrow skin incision in 793 cases for treatment of 989 @entity438 . Of @entity1 , 474 were operated on after @entity510 , and 319 were operated on under elective conditions. After lateral frontobasal burr hole trephination, a limited subfrontal craniotomy was created. To achieve adequate intraoperative exposure through the limited approach, endoscopes were used routinely. Surgical outcome was assessed using the modified Rankin scale. RESULTS: The transcranial endoscope-assisted microneurosurgery technique was used routinely via a supraorbital approach. In 152 operations (19.1%), the endoscope provided important visual information in the vicinity of the @entity439 , revealing subsequent clip repositioning. The results of incidental @entity439 were excellent with a modified Rankin scale score  <=2 in 96.52%. The overall outcome of @entity1756 was good with a modified Rankin scale score  <=2 in 72.2% of @entity1 . There were no approach-related @entity260 . CONCLUSIONS: The minimally invasive supraorbital keyhole approach allowed safe surgical treatment of @entity438 , including after @entity510 . The markedly improved endoscopic visualization increased the assessment of clip placement with ideal control of surrounding vessels including perforators for identification of incorrect clip position.
