随着高分辨CT、MRI的进步和显微手术的普及,听神经瘤的手术效果显著改善,但保留颅神经后其神经功能的长期结果如何未见报导.作者报告6年来听神经瘤全切术保留面神经、听神经后其机能和预后的研究结果.行听神经鞘瘤全切17例,年龄32～63岁,术后观察2～51月,平均9.4月.肿瘤1cm左右,局限于内听道者5例,2cm以内2例,3cm以内5例,3cm以上5例.14例为实质性,3例为囊性.面神经麻痹采用90分计分法,术前轻度麻痹者4例,术后所有患者的面神经都做到解剖保留,其机能、预后与肿瘤大小的关系表现为:内听道内5例术后 With the advancement of high-resolution CT, MRI, and the popularity of microsurgery, the surgical outcome of acoustic neuromas has improved significantly. However, there have been no reports of long-term neurological outcomes after preservation of cranial nerves. The authors reported that acoustic neuroma was preserved for 6 years. After the facial nerve and auditory nerve function and prognosis, we performed total excision of 17 cases of nerve schwannomas, aged 32-63 years old, and observed postoperatively from 2 to 51 months, with an average of 9.4 months. Tumors were approximately 1 cm, and were limited to the inner auditory 5 Cases, 2cm within 2cm, 5cm within 3cm, 5cm above 3cm, 14 cases were substantial, 3 cases were cystic. 90 cases of facial nerve palsy were scored, 4 cases were mild paralysis before operation, all were postoperative The patient’s facial nerve was anatomically preserved. The relationship between its function, prognosis, and tumor size was as follows: 5 cases within the internal auditory canal.
