Endoscopic Skull Base Surgery

Abstract

Endoscopic skull base surgery has undergone rapid advancement in the past decade moving from pituitary surgery to suprasellar lesions and now to a myriad of lesions extending from the cribriform plate to C2 and laterally out to the infratemporal fossa and petrous apex. Evolution of several technological advances as well as advances in understanding of endoscopic anatomy and the development of surgical techniques both in resection and reconstruction have fostered this capability. Management of benign disease via endoscopic methods is largely accepted now but more data is needed before the controversy on the role of endoscopic management of malignant disease is decided. Continued advances in surgical technique, navigation systems, endoscopic imaging technology, and robotics assure continued brisk evolution in this expanding field.

Anatomical and computed tomographic analysis of the transcochlear and endoscopic transclival approaches to the petroclival region

“…Anteromedial access was achieved successfully on four cadaveric specimens with the EEA. Each of the dissections created unobstructed views of the anteromedial skull base, which was consistent with prior studies of endonasal anatomy . The anatomy of the posterior wall of the sphenoid sinus consistently contained the easily recognizable optic carotid prominence and recess, facilitating identification and dissection of the clivus inferiorly.…”

Olfactory groove meningioma: Discussion of clinical presentation and surgical outcomes following excision via the subcranial approach

“…Over the past decade, the applications of skull base endoscopic surgery have steadily expanded 16. Possible technical advantages include early tumor devascularization, direct tumor access without brain retraction or exposure, and minimal manipulation of neurovascular structures including the optic nerve 17–20.…”

Moderne Schädelbasischirurgie aus Sicht des Neurochirurgen

“…Im Moment scheint der neueste Trend der Einsatz von Endoskopiesystemen im Bereich der Schädelbasischirurgie zu sein [2,12,16]. Die Grundidee ist richtig und stellt damit einen weiteren konsequenten Versuch dar, die operativen Zugänge zur Schädelbasis zu reduzieren und zu miniaturisieren.…”

“…Die Grundidee ist richtig und stellt damit einen weiteren konsequenten Versuch dar, die operativen Zugänge zur Schädelbasis zu reduzieren und zu miniaturisieren. Die Anzahl an Veröffentli-chungen von endoskopischen Zugängen und endoskopischen operativen Techniken im Bereich der Schädelbasis ist in den letzten Jahren sprunghaft angestiegen [9,12]. Betrachtet man die Historie der letzten Jahrzehnte bei Operationen an der Schä-delbasis, ist dieser Trend nachvollziehbar.…”
