The extended eyebrow approach a cadaveric stepwise dissection

Abstract

Background: The eyebrow incision supraorbital approach is limited by the lack of exposure of the sylvian fissure exposure. By extending the skin incision 15 mm posteriorly and the supraorbital craniotomy beneath the superior temporal line, proximal sylvian dissection is achievable, and the surgical exposure is drastically improved. Methods: Throughout a cadaveric stepwise dissection and a pertinent anatomical analysis, we describe in detail the surgical technique of the extended eyebrow approach (xEBA). We additionally highlight main anatomical elements involved in this approach and provide technical nuances to avoid complications. Conclusion: xEBA is a versatile technique that uses the pretemporal, transylvian, and subfrontal corridor to enhance surgical exposure around the anterior cranial fossa.
