Extracting the Cochlea from a Human Temporal Bone: A Cadaveric Protocol

This method is significant because it demonstrates how cochlea can be obtained for research purposes from cadaver temporal bone by following key anatomical structures inside the cochlea. This technique involves heavy surgical drilling. Learning this process might take practice and cause a risk of cochlear trauma.

Additionally, the temporal bone anatomy can be challenging for first timers. The visual demonstration of this method provides technical insight in the drilling and exposure of the anatomical landmarks, which cannot be presented in written or image form as good as in video form. Start by opening the facial recess between the facial nerve and the external ear canal with a two millimeter diamond bur.
