Transnasal Endoscopy-Assisted Skull Base Surgery

Abstract

Skull base surgery (SBS), which originated in the 19th century, became refined in the 20th century in parallel with technological advancements and is now in the midst of further refinements largely driven by advances in endoscopic sinus surgery. With the development of modern SBS, lesions that were once inoperable and potentially fatal can now be eradicated successfully by means of endoscopy-assisted procedures that reduce or completely eliminate intracranial trauma, minimize postsurgical morbidity, and make full recovery possible. It is absolutely mandatory to have the appropriate instrumentation for endoscopy-assisted SBS. Among the new technologies available are advanced endoscopes, high-speed suction irrigation drills, digital video cameras, computed tomography and magnetic resonance imaging, and systems for 3-dimensional computer-assisted image-guided surgical navigation. An experienced endoscopic surgeon working with multidisciplinary teams, and using new instrumentation and techniques, can bring SBS to new levels of success in the 21 st century.
