This study describes the endoscopic anatomy of the cerebellopontine angle (CPA). Endoscopes were introduced into the basal cisterns and it was found that the neurovascular structures of this angle could be seen in detail. ⋯ The need for minimally invasive surgery may mandate further study of the application of this type of endoscopy in surgical practice. It is stressed that considerable cadaver experience should be obtained with this technique prior to any application in the operating room.
