This article reports 153 cases from the cranial fossa approach to the petrous apex and internal auditory canal resection vestibular nerve treatment of dizziness, facial nerve lesions and removal of intra-canal surgery and other surgical indications, methods and complications. Surgical methods: The patient supine anesthesia, from the front of the ear before the steering wheel to the front of the temple for a slight “7” -shaped incision, separation of the temporalis and temporal fascia, pay attention not to damage facial nerve branches. Drills were cut open 3 × 4 cm ~ 2 square temporal bone flap, the meninges inward separation, with skull midfinger retractor to pull the meninges and temporal lobe, pay attention not to damage the geniculate ganglion. At this time bow arching and shallow petrous nerve can be identified. Locating the internal auditory canal is the key to surgery, the most commonly used House’s method, that is
