Many materials such as fascia, cartilage have been used for the reconstruction of the ear drum. Cartilage retains its rigidity and resists retraction, resorption and reperforation, even in cases with eustachian tube dysfunction. The hearing gain and uptake rate of cartilage is comparable to that of temporalis fascia.
To compare hearing outcome amd graft uptake rate between temporalis fascia graft & cartilage graft.
A Quazi experimental study was conducted between January 2019-April 2020 in 52 patients who underwent Type 1 Tympanoplasty. 26 patients underwent Cartilage tympanoplasty & 26 underwent tympanoplasty with Temporalis fascia as graft. All patients underwent pure tone audiogram before surgery & 3 months after tympanoplasty and we compared the graft uptake and hearing outcome in both groups.
In Group A out of 26 patients who underwent temporalis fascia as graft, 2 patients had residual perforation. In group B out of 26 patients who underwent cartilage Tympanolasty 1 patient had residual perforation. In Group A 11 patients had hearing gain more than 10db. In Group B 12 patients had hearing gain more than 10 db.
Temporalis fascia & cartilage perichondrium are equally good as graft material & we should select the graft material according to the cases.
许多材料如筋膜、软骨已被用于鼓膜重建。软骨即使在咽鼓管功能障碍的情况下也能保持其刚性,抵抗回缩、吸收和再穿孔。软骨的听力增益和吸收率与颞肌筋膜相当。
比较颞肌筋膜移植与软骨移植的听力结果和移植物吸收率。
2019年1月至2020年4月对52例行Ⅰ型鼓室成形术的患者进行了一项半实验性研究。26例患者接受软骨鼓室成形术,26例接受颞肌筋膜移植鼓室成形术。所有患者在手术前及鼓室成形术后3个月均接受纯音听力图检查,我们比较了两组的移植物吸收情况和听力结果。
在接受颞肌筋膜移植的26例A组患者中,2例有残余穿孔。在接受软骨鼓室成形术的26例B组患者中,1例有残余穿孔。A组11例患者听力增益超过10dB。B组12例患者听力增益超过10dB。
颞肌筋膜和软骨膜作为移植物材料同样良好,我们应根据具体情况选择移植物材料。
