Perspectives on Endoscopic Transseptal Interforniceal Approach for Retroforaminal Colloid Cysts.

World Neurosurg 2021 08 8;152:e71-e80. Epub 2021 May 8.

Department of Neurosurgery, Cairo University, Cairo, Egypt.

Background: Although the interforniceal approach with the preservation of the fornix is useful during the endoscopic approach for retroforaminal colloid cysts, it carries a significant risk of memory and cognitive difficulties. Because most reports have reported the endoscopic approach to colloid cysts through the foramen with little emphasis on retroforaminal cysts, the aim of this study was to investigate colloid cysts as a special entity with regard to their different characteristics and surgical approaches and outcomes.

Methods: In this retrospective study, 12 patients with third ventricular colloid cysts with retroforaminal extensions were included. Read More

Neurosurg Rev 2021 Aug 12;44(4):2369-2377. Epub 2020 Oct 12.

Department of Neurological Surgery, Wexner Medical Center, The Ohio State University College of Medicine, 410 W 10th Ave, N-1011 Doan Hall, Columbus, OH, 43210, USA.

The use of minimally invasive transcranial ports for the resection of deep-seated lesions has been shown to be safe and effective. To date, most of the literature regarding the tubular retractors used in brain surgery is comprised of individual case reports that describe the successful resection of deep-seated lesions such as thalamic pilocytic astrocytomas, colloid cysts in the third ventricle, hematomas, and cavernous angiomas. The authors describe their experience using a tubular retractor system with three different cases involving large intraventricular meningiomas and examine radiographic and patient outcomes.
