Supraorbital transciliary keyhole approach for removal of tuberculum sellae meningioma: 3D surgical video.

Surg Neurol Int 2021 5;12. Epub 2021 Jan 5.

Department of Neurosurgery, Northeast National Medical Center, Monterrey, Nuevo Leon, Mexico.

Background: Tuberculum sellae meningiomas have an incidence from 5 to 10% of all intracranial meningiomas[2] and tend to be surgically difficult and challenging tumors given their proximity to important structures such as the internal carotid artery (ICA), anterior cerebral artery (ACA), and optic nerves.[3] Typically, their growth is posteriorly and superiorly oriented, thereby displacing the optic nerves and causing visual dysfunction, which is the primary indication for surgical treatment.[1] The main goals of the treatment are the preservation or restoration of visual abilities and a complete tumor resection.

Department of Neurosurgery Department of Pathology Department of Obstetrics and Gynecology Department of Radiology, Chonnam National University Hwasun Hospital and Medical School, Hwasun, Jeollanam-do, South Korea.

Despite the advances in the microsurgical technique and anatomical understanding of the anterior and middle skull base, anterior clinoidal meningiomas are still challenging lesions to resect completely and safely due to their intimate relationship with vital neurovascular structures. We report predictive factors for tumor recurrence and postoperative complications based on surgical outcome of patients with anterior clinoidal meningiomas treated at our institution.Fifty-nine consecutive patients with anterior clinoidal meningioma who were surgically treated between March, 1993, and July, 2015, were reviewed retrospectively.

Endoscopic supraorbital eyebrow approach for the surgical treatment of extraaxialand intraaxial tumors.

Neurosurg Focus 2014 ;37(4):E20

Centre for Minimally Invasive Neurosurgery, Prince of Wales Private Hospital, Sydney, Australia.

Object: The supraorbital eyebrow approach is a minimally invasive technique that offers wide access to the anterior skull base region and parasellar area through asubfrontal corridor. The use of neuroendoscopy allows one to extend the approach further to the pituitary fossa, the anterior third ventricle, the interpeduncular cistern, the anterior and medial temporal lobe, and the middle fossa. The supraorbital approach involves a limited skin incision, with minimal soft-tissue dissection and a small craniotomy, thus carrying relatively low approach-related morbidity. Read More

Neurosurg Focus 2013 Jan;34(1 Suppl):Video 1

Department of Neurological Surgery, Center for Skull Base and Pituitary Surgery, Neurological Institute of New Jersey, University of Medicine and Dentistry of New Jersey, New Jersey Medical School, Newark, New Jersey 07101, USA.

Retrochiasmatic third ventricular craniopharyngiomas are formidable tumors to remove surgically. Access to the third ventricle can be achieved through the lamina terminalis corridor. A skull base approach to the lamina terminalis can be performed using either an anterolateral approach (orbitozygomatic, pterional, supraorbital) or a midline approach (extended transbasal, subfrontal).

The minimally invasive supraorbital subfrontal key-hole approach for surgical treatment of temporomesial lesions of the dominant hemisphere.

Minim Invasive Neurosurg 2009 Aug 16;52(4):163-9. Epub 2009 Oct 16.

Neurosurgical Department, University Hospital Zurich, Zurich, Switzerland.

Introduction: Surgery in the temporomesial region is generally performed using a subtemporal, transtemporal, or pterional-transsylvian approach. However, these approaches may lead to approach-related trauma of the temporal lobe and frontotemporal operculum with subsequent postoperative neurological deficits. Iatrogenic traumatisation is especially significant if surgery is performed in the dominant hemisphere. Read More
