Neurosurgery (Skull Base Approaches)

Course Objectives

The objective of this surgical course is to improve patient care. Upon completion of this course, participants will be able to:

  • Identify principles of various skin flaps and craniotomies
  • Describe cavernous sinus anatomy and surgical exposure
  • Describe and better understand various commonly used anterior, middle and posterior cranial fossa skull base approaches
  • Review Lateral skull base anatomy and surgical exposures
  • Identify temporal bone anatomy and specify transpetrosal surgical approaches

Target Audience

Practicing neurosurgeons, otolaryngologists, fellows, and residents in training.
