Anatomy, ultrastructure, electrophysiology, and clinical functions of the nervus intermediu. Usefulness in cerebellopontine pathology

Background: Although previous studies have described the clinical features of the nervus intermedius (NI), no attempt has yet been made to describe the relationship between the anatomical, ultrastructural, and electrophysiological characteristics of the nervus intermedius. Objective: In this study, we analyzed the intraoperative electrophysiological response obtained during vestibular schwannoma surgery. Cadaveric anatomical dissections were performed to compare the results. Ultrastructure was studied using electron microscopy. Materials and Methods: Thirty-six consecutive patients underwent microsurgery for ves…
