Abstract

For surgeries for tumors in the cerebellopontine angle (CPA), such as vestibular schwannoma, and for microvascular decompression (MVD) for hemifacial spasm (HFS) a detailed knowledge of the microsurgical anatomy of the internal auditory canal (IAC) and related neurovascular complex around the porus acusticus internus (PAI) is essential [8, 11, 20–22]. This knowledge enables detailed understanding of the preoperative images, leading to accurate preoperative pr and intraoperative identification of the nerves, e.g., cranial nerves (CNs) VII and VIII, and blood vessels [20, 22].
