We aim to compare the functional and anatomical outcomes of temporalis muscle fascia graft with that of full thickness composite tragal island cartilage graft in patients who are undergoing Type 1 Tympanoplasty. This is a prospective study conducted on 60 patients. Patients who underwent type 1 tympanoplasty were included in the study. Patients were divided into Group A (temporalis fascia graft) and Group B (tragal island cartilage) with 30 patients in each. Out of the 60 patients, 18 females and 12 males belonged to Group A, 20 females and 10 males belonged to Group B. The mean age group was between 31 and 40 yrs in both the groups. The mean hearing gain and ABG closure for Group A was 13.83 ± 8.11 and 13.39 ± 7.44 and in Group B it was 11.17 ± 4.06 and 11.5 ± 5. The graft uptake rate of Group A was 90% and Group B was 96.67%. The wound healing rate of Group A was 93.33% and Group B was 100%. The mean duration of surgery in Group A was 97.5 ± 17.16 and in Group B was 81.33 ± 11.14. Both the groups had significant post-operative improvement in hearing. No significant results found between both the groups in terms of hearing gain, air-bone gap closure, wound healing and graft uptake rate except lesser duration of surgery in group B. We conclude that tragal island cartilage graft is a better choice in Type 1 Tympanoplasty.
我们旨在比较在接受I型鼓室成形术的患者中，颞肌筋膜移植与全层复合耳屏岛状软骨移植的功能和解剖学结果。这是一项针对60例患者进行的前瞻性研究。接受I型鼓室成形术的患者被纳入研究。患者被分为A组（颞肌筋膜移植）和B组（耳屏岛状软骨移植），每组30例。在这60例患者中，A组有18名女性和12名男性，B组有20名女性和10名男性。两组的平均年龄均在31至40岁之间。A组的平均听力增益和气骨导差闭合分别为13.83±8.11和13.39±7.44，B组分别为11.17±4.06和11.5±5。A组的移植物吸收率为90%，B组为96.67%。A组的伤口愈合率为93.33%，B组为100%。A组的平均手术时长为97.5±17.16，B组为81.33±11.14。两组术后听力均有显著改善。除了B组手术时间较短外，两组在听力增益、气骨导差闭合、伤口愈合和移植物吸收率方面均未发现显著差异。我们得出结论，在I型鼓室成形术中，耳屏岛状软骨移植是更好的选择。
