耳神经外科手术进路包括经颅中窝、迷路后、经迷路和枕下迷路联合进路等数种。经颅中窝进路为锯开颞骨鳞部,拉开颞叶,看清弓状隆起,沿隆起前内方用金刚石电钻磨开内耳道顶壁,在其稍后部切开硬脑膜,避免伤及面神经,暴露位听神经,可作前庭神经切断术、面神经颅内段手术、早期听神经瘤切除术、Fisch氏内耳道手术、岩浅大神经切除术、咽鼓管重建术及治疗中间神经痛和膝状神经痛。熟悉内耳道及其邻近解剖十分重要,偶有不慎,向后可损伤上半规管,向前可破坏耳蜗,造 Otorhinolaryngeal surgical approaches include transcranial mid-tibial fossa, labyrinthine, combined maze via labyrinthine and suboccipital labyrinth. Transcranial fossa into the pit for the sawing of the temporal bone squamous cell, opened the temporal lobe, see the bow-like bulge, along the inside before the bulge with diamond drill to open the inner ear canal, the latter part of the dural incision, to avoid Injury and facial nerve exposure of the auditory nerve can be used for vestibular neurotomy, facial nerve intracranial surgery, early acoustic neuroma resection, Fisch’s internal auditory canal surgery, shallow petrous excision, eustachian tube reconstruction and treatment of intermediate neuralgia and Genital nerve pain. Familiar with the internal auditory canal and its adjacent anatomy is very important, occasionally inadvertently, the back can damage the upper semicircular canal, forward can damage the cochlea, made
