Ahead of Print: Endoscopic Colloid Cyst Resection in the Absence of Ventriculomegaly

Background: The absence of ventriculomegaly has been considered an overt or relative contraindication to the endoscopic resection of colloid cysts. In the past, endoscopic removal of colloid cysts in the absence of ventriculomegaly has been considered ill advised. Reports of successful endoscopic surgery in small ventricles are surfacing

Objective: We examined the combined experience of 2 high-volume endoscopic centers to characterize the outcomes of patients undergoing endoscopic removal of colloid cysts in small ventricles.

Methods: We retrospectively reviewed all endoscopic colloid cyst removal procedures by the 2 senior authors (PN, CT) performed at the Barrow Neurological Institute over an 8-year period. Radiographic, clinical, and interview data were recorded and analyzed. The age-adjusted relative bicaudate index was used to define “small ventricles.”

Free Article: Endoscopy in Aneurysm Surgery

Background: Surgical clipping with complete occlusion of the aneurysm and preservation of parent, branching, and perforating vessels remains the most definitive treatment for intracranial aneurysms.

Objective: To evaluate the benefit of endoscopic application during microsurgical procedures in a retrospective study.

Methods: One hundred eighty aneurysms were microsurgically treated in 124 operations. Three different applications of endoscopic visualization were used, depending on the respective requirements: inspection before clipping, clipping under endoscopic view, and postclipping evaluation.

Ahead of Print: Endoscopic Middle Cranial Fossa Reconstruction

Background: Reconstruction of the skull base is essential to prevent postoperative leakage of cerebrospinal fluid (CSF). However, a reliable method of reconstructing the middle cranial fossa via a subtemporal keyhole is not available.

Objective: To determine whether less invasive reconstruction of the middle cranial fossa under endoscopic guidance using a pedicled deep temporal fascia approach via a subtemporal keyhole is feasible and useful.

Methods: The middle cranial fossa in four fresh cadaver heads was reconstructed using a 4-mm 0[degrees] rigid endoscope.
