Primary Sellar Abscesses: A Systematic Review and 2 Rare Observations.

Background: Abscesses of the chiasmatic-sellar region are quite rare and are often a result of surgical intervention, trauma, or tumor growth. Primary abscesses are extremely rare and represent a group of abscesses the occur because of internal microbial seeding. Primary abscesses are rarely reported.

Surgical Correction of a Clivus Cerebrospinal Fluid Fistula: A Technical Report.

Background: Cerebrospinal fistulas of the clivus region often result from previous surgical intervention at the skull base. The localization and size of the fistula determine the appropriate treatment strategy. When flap closure is not possible, the microsuture technique with autograft placement provides a favorable outcome.

Endoscopic Transsphenoidal Approach in Treatment of Germinomas of the Chiasmosellar Region.

Introduction: Germinogenic central nervous system (CNS) tumors represent a heterogeneous group of tumors, constituting approximately 0.4% of all primary brain tumors. Removal of the tumor has no prognostic value.

Anatomical Aspects of the Transnasal Endoscopic Access to the Craniovertebral Junction.

Objective: Interest in endoscopic transnasal access has increased with continued technological advances in endoscopic technology. The goals of this study were to review the normal anatomy in transnasal endoscopic neurosurgery and outline the anatomical basis for an expanded surgical approach. Defining anatomical aspects of surgical endoscopy helps guide the surgeon by defining normal anatomy of the access vector.
