Abstract

Objective

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.

Methods

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.

Results

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.

Conclusion

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.

Level of evidence

Level 4.

I 型鼓室成形术中的改良非对称软骨-软骨周围岛状移植：784例患者的回顾性分析。

研究目的本研究旨在评估新型改良非对称软骨-软骨岛移植物在鼓室成形术中的疗效。该设计的特点是前段比后段长，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 名接受初级 I 型鼓室成形术的慢性中耳炎患者，他们都采用了改良的非对称软骨-软骨岛移植技术。术前评估了所有患者的人口统计学和特征、术前穿孔位置和纯音测听（PTA），并在 12 个月的随访中评估了移植成功率和术后听力结果：这项研究评估了鼓室成形术中改良非对称软骨-软骨外岛移植的疗效。在 784 名患者中，术后 12 个月的平均气骨间隙（ABG）改善了 17.3 分贝，移植成功率为 99%。术前 ABG 从 24 分贝明显改善到术后的 6.6 分贝（p 结论：鼓室成形术是一种有效的鼓室成形术：鼓室成形术为恢复听力功能和预防复发性耳聋提供了一种行之有效的手术方法。非对称软骨-软骨岛移植设计已成为鼓室成形术中实现最佳功能和解剖效果的一种有前途的技术：证据等级：4级。

期刊介绍： Brazilian Journal of Otorhinolaryngology publishes original contributions in otolaryngology and the associated areas (cranio-maxillo-facial surgery and phoniatrics). The aim of this journal is the national and international divulgation of the scientific production interesting to the otolaryngology, as well as the discussion, in editorials, of subjects of scientific, academic and professional relevance. The Brazilian Journal of Otorhinolaryngology is born from the Revista Brasileira de Otorrinolaringologia, of which it is the English version, created and indexed by MEDLINE in 2005. It is the official scientific publication of the Brazilian Association of Otolaryngology and Cervicofacial Surgery. Its abbreviated title is Braz J Otorhinolaryngol., which should be used in bibliographies, footnotes and bibliographical references and strips.
