Advantages and Disadvantages of the Supraorbital Keyhole Approach to Intracranial Aneurysms

The fundamental tendency to be as minimally invasive as possible and to achieve a maximum of efficacy in the treatment of patients has existed since the beginning of surgery. In treating intracranial aneurysms the most widely used approach is pterional or frontotemporal approach described by Yasargil. The increasing knowledge of microsurgical anatomy, improved preoperative diagnostic techniques, and well adapted microsurgical instruments have led to the development of minimally invasive approaches. The supraorbital keyhole approach via an eyebrow incision is one of these minimally invasive procedures. Since it was first described by Perneczky it has raised debates on its advantages and disadvantages. The authors present their experience in using the supraorbital keyhole approach in treating intracranial aneurysms.
