To investigate the outcomes of graft uptake and hearing results in the repair of anterior perforation via a total endoscopic transcanal approach using a single or double perichondrium reinforced cartilage underlay technique.
Retrospective study.
Tertiary referral hospital.
We analyzed 65 patients who underwent surgery for anterior perforation. All surgeries were done via an endoscopic transcanal approach using tragal cartilage as graft, underlay technique reinforced with single or double perichondrium. Two groups were created in which group A had single perichondrium reinforcement and group B had double perichondrium. Graft uptake and hearing outcomes were evaluated between the two groups.
During the study period, 65 patients were included, of which 3 were lost to follow-up, and thus, only 62 patients were assessed. As for the surgical outcome, graft uptake was observed in 95.2% (n = 59) of patients, 6 months after the intervention. Graft uptake was not statistically significantly different between groups A and B and was 95% in both. There was a statistically significant improvement in hearing across the series overall, with no significant differences seen between group A and group B.
The endoscopic approach for myringoplasty offers superior visualization, especially for anterior perforation avoiding postaural approach and canaloplasty. Endoscopic single or double perichondrium reinforced cartilage underlay technique is a reliable method for repair of anterior perforation. There is no difference in using single or double perichondrium reinforcement. Thus, we recommend using single or double perichondrium reinforcement depending on the need during the surgery.
通过经耳道全内镜入路,使用单层或双层软骨下软骨膜加强技术,研究修复前穿孔的移植物吸收和听力结果。
回顾性研究。
三级转诊医院。
我们分析了 65 例接受前穿孔手术的患者。所有手术均通过经耳道内镜入路进行,使用耳屏软骨作为移植物,采用单层或双层软骨膜下技术进行加强。将患者分为两组,A 组为单层软骨膜加强,B 组为双层软骨膜加强。比较两组之间的移植物吸收率和听力结果。
在研究期间,共纳入 65 例患者,其中 3 例失访,因此仅评估了 62 例患者。就手术结果而言,干预后 6 个月,有 95.2%(n=59)的患者出现移植物吸收。A 组和 B 组的移植物吸收率无统计学差异,均为 95%。整个系列的听力均有统计学显著改善,A 组和 B 组之间无显著差异。
鼓膜成形术的内镜入路提供了更好的可视化效果,特别是对于避免后鼓室入路和耳道成形术的前穿孔。内镜单层或双层软骨膜下软骨加强技术是修复前穿孔的可靠方法。使用单层或双层软骨膜加强的效果没有差异。因此,我们建议根据手术需要,使用单层或双层软骨膜加强。
