Objective:This study investigated the application of combined ossicular replacement prosthesis（The Kurz Omega Connector+TORP） in type Ⅲ tympanoplasty, and compared the surgical effect with traditional TORP. Methods:Twenty patients with unilateral chronic suppurative otitis media diagnosed in the Department of Otorhinolaryngology, Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2019 to June 2020 were included in this study.All the patients were treated with intra-auricular incision with a microscopic approach（tympanic exploration, lesion clearance+type Ⅲ tympanoplasty）. According to the placement of different types of ossicular replacement prosthesis in the ossicular chain reconstruction of type Ⅲ tympanoplasty, the patients were divided into two groups: the traditional TORP group（n=10） and the combined ossicular replacement prosthesis（The Kurz Omega Connector+TORP） group（n=10）. All patients underwent pure tone audiometry before and 1 year after the operation, and the average hearing threshold and air-bone conduction difference（ABG） were compared between the two groups before and after the operation. Results:The reconstruction of the ossicular chain was completed successfully in all patients. Endoscopic examination showed that the epithelialization of the operative cavity was good and the repair of the tympanic membrane recovered well one month after the operation. There was no significant difference in preoperative mean airway threshold between the combined ossicular replacement prosthesis and the traditional TORP group （74.13[41.50，80.50] dB vs 74.25[44.81，82.50] dB, P>0.05）, there was no significant difference in preoperative ABG （55.63[21.50，61.25] dB vs 54.13[23.63，60.38] dB, P>0.05）. After the operation, the ABG of the combined auriculus group was significantly lower than that of the traditional operation group （12.00[5.75，24.56] dB vs 34.88[14.19，46.44] dB, P<0.05）. Conclusion: The combined ossicular replacement prosthesis（The Kurz Omega Connector+TORP） can increase the stability of hearing reconstruction and improve hearing in type Ⅲ tympanoplasty.
目的：探讨Ω钛质底板+全听小骨（TORP）在Ⅲ型鼓室成形术的应用，并与传统TORP人工听骨术后疗效进行比较。 方法：纳入2019年1月—2020年6月于中山大学孙逸仙纪念医院耳鼻咽喉科确诊为单侧慢性化脓性中耳炎患者20例，均行耳内切口显微镜下手术治疗（鼓室探查术，病变清除+Ⅲ型鼓室成形术），Ⅲ型鼓室成形术的听骨链重建根据放置不同类型的听小骨分为常规TORP组10例和Ω钛质底板+TORP组（组合听小骨组）10例。所有患者术前及术后1年行纯音测听，比较两组患者术前术后的平均听阈及气骨导差（ABG）。 结果：所有患者听骨链重建均顺利完成，术后1个月内耳内镜检查显示术腔上皮化良好，修补鼓膜恢复良好。术后纯音测听显示，组合听小骨组与常规TORP组患者术前气导纯音听阈分别为74.13（41.50，80.50） dB和74.25（44.81，82.50） dB，差异无统计学意义（P>0.05）；术前ABG分别为55.63（21.50，61.25） dB和54.13（23.63，60.38） dB，差异无统计学意义（P>0.05）；术后ABG分别为12.00（5.75，24.56） dB和34.88（14.19，46.44） dB，差异有统计学意义（P<0.05）。 结论：组合Ω底座与全人工听小骨能增加听力重建的稳定性，提高Ⅲ型鼓室成形术的听力效果。.
