听神经瘤膜性结构与坐位显微手术的关系

The relationship between the membranous structures of acoustic neuromas and microsurgery in sitting position

听神经瘤是源于前庭神经的良性肿瘤,绝大多数肿瘤位于桥小脑角附近。对于临床症状明显,随访中肿瘤逐渐增大,压迫周围脑组织的听神经瘤,目前最好的治疗方式是手术治疗。由于桥小脑角神经、血管丰富,如何完整切除肿瘤又避免对周围脑组织、神经、血管损伤是手术治疗的关键。随着对听神经瘤周围膜性结构的深入研究,我们认为,了解听神经瘤周围膜性结构的组成及其与肿瘤的关系,利用其膜性结构在手术中的特点,通过一定技巧保护所有术中膜样组织,可能是既能尽量完整切除肿瘤组织,又避免对肿瘤周围组织造成伤害导致术后神经功能缺失的重要环节,利用听神经瘤膜性组织可能是切除听神经瘤的重要方式。

Acoustic neuroma is a kind of benign tumor originating from the vestibular nerve,and most tumors are located near the cerebellopontine angle.For acoustic neuromas with obvious clinical symptoms,tumors gradually increasing during follow-up,and pressure on the surrounding brain tissue,the best treatment is surgery.However,due to the abundant nerves and blood vessels in the cerebellopontine angle,how to remove the tumor completely and avoid damage to the surrounding brain tissue,nerve,and blood vessel is the key to surgical treatment.With the in-depth research on the membranous structures surrounding acoustic neuroma,we believe that understanding the composition of the membranous structures surrounding the acoustic neuroma and its relationship with the tumor,useing the characteristics of the membranous structures,and protecting all the membranous structures through certain techniques during surgery,maybe an important way to remove the tumor tissue as completely as possible and avoid damage to the surrounding tissues of the tumor resulting in postoperative neurological loss.The use of the membranous structures of acoustic neuromas may play a crucial to role in removing acoustic neuroma.
