听神经瘤膜性结构及其在听神经瘤手术治疗中的作用研究进展

Recent advances in membranous structures of acoustic neuromas and their role in surgical treatment of acoustic neuromas

目前研究发现听神经瘤绝大部分属于蛛网膜下腔肿瘤,蛛网膜外肿瘤少见。然而,随着人们对听神经瘤膜性结构的进一步深入研究,发现听神经瘤表面的膜结构可能由蛛网膜、前庭神经束膜、退化的前庭神经纤维及硬膜样纤维组织等共同构成。结合听神经瘤膜性结构特点,采取合适的手术策略进行显微操作,对肿瘤的切除和患者神经功能的保留相当重要。笔者现围绕听神经瘤膜性结构特点及其手术治疗的研究进展进行综述,并提出膜性结构在听神经瘤手术治疗中的作用。

At present,most scholars have found that majority of acoustic neuromas are subarachnoid tumors,and extra-arachnoid tumors are rare.However,with the further study of the membranous structures of the acoustic neuromas,it has been found that the membrane structures of the surface of the acoustic neuromas may be composed of arachnoid membrane,vestibular nerve membrane,degraded vestibular nerve fibers,and dural fibrous tissues.Combined with the characteristics of membrane structure of the acoustic neuromas,it is very important to adopt appropriate surgical strategies to perform micromanipulation on tumor resection and nerve function preservation.This article reviews the characteristics of the membrane structures of the acoustic neuromas and their surgical treatment,and proposes the role of the membrane structure in surgery.
