To compare clinical and audiological outcomes of the type 1 tympanoplasties where conchal cartilage (island graft) and temporalis fascia were used as the graft material.
In this retrospective study, the results of type 1 tympanoplasty operations (n = 50) in which cartilage and temporalis fascia were used for graft material were compared.
Pre- and postoperative otoscopic findings of both groups were similar (p > 0.05). Preoperatively, the pure tone averages (PTAs) and hearing thresholds of the fascia and cartilage groups were similar (p > 0.05). However, postoperatively, the PTAs and air-bone gap closure were better with temporalis fascia compared to cartilage grafting (p < 0.05). On frequency-specific comparisons, the pure tone thresholds at the frequencies of 0.5, 1 and 2 kHz recovered better with temporalis fascia compared to cartilage (p < 0.05). Although the pure tone recovery was better at 4 kHz with temporalis fascia, the difference between the groups were not significantly different (p > 0.05).
In conclusion, in contrast to many reports in the literature, temporalis fascia grafting seems better in our study than grafting with conchal cartilage.
比较使用耳甲软骨（岛状移植物）和颞肌筋膜作为移植材料的Ⅰ型鼓室成形术的临床和听力学结果。
在这项回顾性研究中，比较了使用软骨和颞肌筋膜作为移植材料的Ⅰ型鼓室成形术（n = 50）的结果。
两组术前和术后的耳镜检查结果相似（p > 0.05）。术前，筋膜组和软骨组的纯音平均听阈（PTA）和听力阈值相似（p > 0.05）。然而，术后，与软骨移植相比，颞肌筋膜组的PTA和气骨导差闭合情况更好（p < 0.05）。在特定频率比较中，与软骨相比，颞肌筋膜在0.5、1和2 kHz频率处的纯音阈值恢复更好（p < 0.05）。尽管颞肌筋膜在4 kHz处的纯音恢复更好，但两组之间的差异无统计学意义（p > 0.05）。
总之，与文献中的许多报道相反，在我们的研究中，颞肌筋膜移植似乎比耳甲软骨移植效果更好。
