This study aimed to assess the efficacy of a novel modified asymmetric chondro-perichondrial island graft in tympanoplasty. The design features a longer anterior segment compared to the posterior segment, addressing limitations of symmetrical grafts. We investigated the impact of this modified graft on hearing improvement and graft success rates in patients undergoing tympanoplasty surgery.
This retrospective study evaluated 784 patients with chronic otitis media who underwent primary type I tympanoplasty with a modified asymmetric chondro-perichondrial island graft technique. Demographics and characteristics of all patients, preoperative location of the perforation, and Pure-Tone Audiometry (PTA) were assessed preoperatively, and graft success and postoperative hearing outcomes were evaluated at the 12-month follow-up.
This study evaluated the efficacy of a modified asymmetric chondro-perichondrial island graft in tympanoplasty. In 784 patients, the mean 12-month postoperative Air-Bone Gap (ABG) improvement was 17.3 dB with a 99% graft success rate. Preoperative ABG significantly improved from 24 dB to 6.6 dB postoperatively (p < 0.001). Perforation location did not affect ABG improvement (p = 0.193) but did influence graft success rate (p < 0.001). No sensorineural hearing loss, retraction pockets, or cholesteatoma were observed postoperatively.
Tympanoplasty offers a well-established surgical approach for restoring hearing function and preventing recurrent otorrhea. The asymmetric cartilage-perichondrium island graft design has emerged as a promising technique to achieve optimal functional and anatomical outcomes in tympanoplasty.

本研究旨在评估一种新型改良不对称软骨 - 软骨膜岛状移植物在鼓室成形术中的疗效。该设计的前段比后段长，解决了对称移植物的局限性。我们研究了这种改良移植物对接受鼓室成形术患者听力改善和移植物成功率的影响。
这项回顾性研究评估了784例慢性中耳炎患者，他们接受了采用改良不对称软骨 - 软骨膜岛状移植物技术的I型初次鼓室成形术。术前评估了所有患者的人口统计学和特征、穿孔的术前位置以及纯音听力测定（PTA），并在12个月随访时评估移植物成功率和术后听力结果。
本研究评估了改良不对称软骨 - 软骨膜岛状移植物在鼓室成形术中的疗效。在784例患者中，术后12个月平均气骨间隙（ABG）改善为17.3dB，移植物成功率为99%。术前ABG从24dB显著改善至术后的6.6dB（p < 0.001）。穿孔位置不影响ABG改善（p = 0.193），但确实影响移植物成功率（p < 0.001）。术后未观察到感音神经性听力损失、内陷袋或胆脂瘤。
鼓室成形术为恢复听力功能和预防复发性耳漏提供了一种成熟的手术方法。不对称软骨 - 软骨膜岛状移植物设计已成为一种有前景的技术，可在鼓室成形术中实现最佳的功能和解剖学结果。
