由于组织学及临床证实听神经瘤多从上、下前庭神经长出,并且多数是从神经鞘而不是从神经纤维长出的,又具有完整包膜解剖上是可以与面、听神经分离的。因此听神经瘤全切除并保留面、听神经是使术后不留存残疾而达到根治及痊愈的重要课题。听神经瘤的外科治疗,大量的报道首先是提高全切率、减低手术死亡率,后来发展到保留面神经。最 Due to the histological and clinical evidence that acoustic neuroma from the upper and lower vestibular nerve growth, and most are from the nerve sheath rather than from the nerve fibers grow, but also has a complete anatomy of the capsule can be separated from the surface, the auditory nerve. Therefore, complete excision of acoustic neuroma and retain the surface, the auditory nerve is not retained after surgery to achieve radical cure and cure an important issue. Surgical treatment of acoustic neuroma, a large number of reports is to raise the rate of full-cut, reduce surgical mortality, and later developed to retain the facial nerve. most
