Supraorbital Keyhole Approach for Clipping Ruptured Anterior Circulation Aneurysms

The supraorbital approach is an important portal of intracranial entry, which gives access not only to the anterior base, but also to the sellar and parasellar region, and the vessels of the anterior circulation. Essentially miniaturization of the traditional pterional approach, supraorbital keyhole approach places minimalization as an important concept in the neurosurgeon’s armamentarium. Keyhole craniotomy, like neuroendoscopy is the culmination of interplay of knowledge of neuroanatomy, neuroimaging, nature of the vascular lesion, optics and instrumentation, and operative neurosurgical skills.
