Facial nerve anatomy was compared in the rat, rabbit, cat, and pig in an effort to develop a model for facial nerve trauma within the temporal bone. The porcine model was found to have the most suitable anatomy. Landmarks for the nerve were excellent. The pig had a definite facial nerve mastoid segment that was vertical, as in the human, and long enough to allow for performance of sequential procedures on the nerve. It was also large enough for grafting and electrical testing. A detailed description of the advantages of the pig model and the anatomy of the surgical approach to the facial nerve in the porcine model is presented.
