The eyebrow approach for anterior circle of Willis aneurysms

Acta Neurochirurgica (2018) 160:1749–1753

The eyebrow approach is a keyhole technique that gives a wide access to the anterior circle of Willis.

Methods A 4-cm linear incision is placed in the upper limit of the eyebrow and a small supraorbital bone flap is raised. A wide arachnoid dissection is essential to maximize the working space. One or multiple aneurysms may be treated by the same approach.

Conclusions The eyebrow approach is a safe technique for selected aneurysms of the anterior circle of Willis
