The pterional approach is widely used for aneurysm surgery. In the pterional approach, the sphenoid wing is removed as much as possible but the orbit is not opened. We developed a new technique by which the sphenoid wing is more completely removed and the superior orbital fissure (SOF) is opened. When the first burr hole, MacCarty's key hole, is drilled, the upper half exposes the dura matter and the lower half exposes the periorbita. After a frontotemporal bone flap is removed, the sphenoid wing and the posterior part of orbital roof are removed and SOF is opened widely. Our new technique is safe, easy to perform and has many advantages such as a wide surgical field.
