In present world of contemporary techniques of microscopic ear surgery and single handed endoscopic ear surgery, we propose the technique of two handed endoscopic tympanoplasty using endoscope holders. The aim of the study is to evaluate the functional and anatomical results of our technique of endoscopic type 3 cartilage tympanoplasty using endoscope holder. It is a Retrospective Non Randomized Clinical Study. A total of 67 endoscope holder assisted exclusively two handed endoscopic type 3 cartilage tympanoplasties performed from December 2014 to March 2017 with our technique were included in the study. Patients with pars tensa retractions and perforations with absent incus were included in the study. Those with cholesteatoma were excluded from the study. Full thickness tragal cartilage disc of 3 × 3 mm dimensions with a circular slot of 1 mm to fit onto the head of the stapes was used for reconstruction. Tympanic membrane reconstruction was done along with attic reconstruction, using sliced tragal cartilage of 0.5 mm thickness. Patients were assessed at 6, 12 and 24 months for graft status. In early follow up period ranging from 24 to 52 months, the graft take up was seen in 64 ears with three perforations giving a success rate of 95.52%. The pre-operative air-bone gap was 42.6 ± 3.26 dB and the post-operative air-bone gap at 6 months, 1 and 2 years was 18.36 ± 3.46 dB, 19.42 ± 4.32 dB and 19.53 ± 4.33 dB respectively. The study reports good air-bone closure to 20 dB postoperatively following type 3 endoscopic tympanoplasty using endoscope holder. Slotted cartilage graft is definitely an excellent option for ossiculoplasty in cases of absent incus providing a stable assembly. Level of evidence: Level 4.
在当今显微耳外科技术和单手内镜耳外科技术的时代,我们提出了使用内镜固定器的双手内镜鼓室成形术技术。本研究的目的是评估我们使用内镜固定器的内镜3型软骨鼓室成形术技术的功能和解剖学结果。这是一项回顾性非随机临床研究。2014年12月至2017年3月期间,共有67例采用我们的技术、仅在双手内镜辅助下使用内镜固定器完成的3型软骨鼓室成形术纳入本研究。紧张部内陷和穿孔且砧骨缺失的患者纳入研究。胆脂瘤患者被排除在研究之外。使用尺寸为3×3毫米、带有1毫米圆形狭槽以适配镫骨头的全厚耳屏软骨盘进行重建。鼓膜重建与上鼓室重建同时进行,使用厚度为0.5毫米的耳屏软骨切片。在术后6个月、12个月和24个月对患者的移植物状况进行评估。在24至52个月的早期随访期内,64只耳朵的移植物成活,有3只耳朵出现穿孔,成功率为95.52%。术前气骨导差为42.6±3.26分贝,术后6个月、1年和2年的气骨导差分别为18.36±3.46分贝、19.42±4.32分贝和19.53±4.33分贝。该研究报告称,使用内镜固定器的3型内镜鼓室成形术后,气骨导差术后良好地闭合至20分贝。对于砧骨缺失的病例,开槽软骨移植物绝对是听骨成形术的一个极佳选择,可提供稳定的组件。证据级别:4级。
