The surgical treatment of intracranial aneurysms from the pterion approach using small trephining openings

: In the past decade, there has been a clear trend for the use of low-invasive surgical interventions in many divisions of neurosurgery. Since each operation is bound to be followed by tissue traumatization, a decrease in the sizes of skull trepanation should be regarded as a way of reducing the incidence of intra- and extracranial complications. The proposed variant of a pterion access to intracranial aneurysms by using small trepanation holes may substantially decrease the duration of surgical interventions and to avoid postoperative epidural and subdural hematomas without preventing the visualization of arteries in both anterior and posterior Willis' circle and at the same time the variant exerts no negative effect on the possibilities of hemostasis in intraoperative aneurysm rupture. The operation yields a good cosmetic effect.
