内淋巴管阻塞对于梅尼埃病患者来说是一种相对较新的手术方法。在常规乳突切除术后,使用常规钛血夹识别和结扎内淋巴管。目前正在一项随机试验中评估该程序的有效性。

1 内淋巴管阻塞2 是一种新的外科手术,对顽固性梅尼埃病患者可能有效 3。4 这种技术 5 的主要优点是它保留了内耳功能,如平衡和听力 6,同时阻止眩晕发作。7 首先将麻醉装置 8 放置在手术室中患者脚端。

9 将术中神经监测系统 10 的控制面板 11 放置在尽可能远离患者头部的位置。12 在定位患者后,用手术刀 13 在消毒过的耳朵耳廓后面做一个 7 到 8 厘米长的 14 耳后切口 15。16 展开皮下层 17 直到颞肌在颅骨上可见。

18 在岩骨上做一个 U 形切口 19 创建一个 palva 皮瓣。20 用一把镊子和一个呼吸器, 21 从皮层 22 上剥下骨膜,直到看到外耳道。23 在组织层 24 中放置两个涂抹器,露出岩骨。

25 形成一个三角形并穿过皮层 26 以识别乳突细胞。27 将 coddle sigmoid sinus 28 和颅硬脑膜确定为标志。29 确定后颅窝的硬脑膜 30 和水平前庭管的曲率。

31 接下来,找到后半规管 32 和后颅窝的硬脑膜。33 确定水平半规管 35 的突出部 34 并找到唐纳森线 36 以估计内淋巴袋的位置。37 使用金刚石车针,将袋子和硬脑膜上的骨头变薄 38 并将内淋巴袋完全骨架化。

39 去除剩余的骨头,露出硬脑膜。40 使用电梯将硬脑膜抬向大脑,41 暴露后半规管的正中壁 42 以识别内淋巴袋。43 使用电梯,创建一个站点 44 以插入仪器的尖端以夹住管道。

45 在确定正确的夹子适合之后,46 用无菌罩 47 盖住患者,并在不关闭夹子的情况下进行 CT 扫描。48 选择 3D 头下方的协议 20 SDCT 头 micro,49 并跟随激活支架的移动。50 选择在颅骨方向设置的颅骨底座 51 并遵循必要的 3D 激活支架移动步骤。

52 扫描完成后,53 选择预设的 Dyna-CT 头部 petrosa。54 访问图像以检查剪辑 55 的位置是否正确。56 使用电梯取下夹子。

57 合上内淋巴管上的夹子。58 使用 70 厘米长的可吸收聚丝缝合线 59 闭合睑瓣和皮下层。60 使用另一个 70 厘米长的 61 可吸收单丝缝合线,62 应用皮下连续缝合以闭合皮肤。

63 用石膏和绷带覆盖闭合的皮肤和头部。64 在参与研究的 26 名患者中,65 名女性略多于男性,66 名,左耳受影响最大。67 主观主诉的结果,68 内淋巴管阻塞后的结果,如下所示。

69 85% 的患者 70 名患者在手术后眩晕的抱怨较少。71 在袋子上削薄骨头时要格外小心。72 骨下的硬脑膜通常很薄 73 破裂会导致脊髓脑液渗漏。

74 这种技术可能被证明对梅尼埃病有效 75 ,同时保留了内耳功能。
