结论：对于慢性中耳炎（COM）伴听骨链大面积破坏的患者，建议采用圆形窗口植入式漂浮质量传感器（FMT）作为听力康复的首选。目的：探讨全听骨置换术（TORP）与全听骨置换术（RWI）在COM患者听力恢复中的优缺点。患者和方法：38例双侧中度至重度混合性或传导性听力损失（无胆脂瘤和双侧听骨链侵蚀（足板残留））的COM患者交替分配到钛- torp （T-TORP）和RWI， FMT的Medel充满活力的声音桥（MVBS）位于RW位。观察两组患者的治疗效果、术前与术后空气传导增益、语音识别情况，并于术后36个月进行统计学分析。评估两组患者术后解剖情况：1)感染复发，2)假体缩回袋，3)假体挤压率，4)假体移位。结果：两种方法在36个月时均获得良好的功能效果和稳定性。T-TORP的挤出率较低。到目前为止，还没有观察到RWI的挤压现象。在所有调查参数中，RWI与T-TORP的听力结果在统计学上要好得多。
Conclusions: Round window implant (RWI) with a floating mass transducer (FMT) may be suggested as the first choice in hearing rehabilitation for patients with chronic otitis media (COM) and extensive destruction of the ossicular chain. Objective: To investigate the pros and cons of the total ossicular replacement prosthesis (TORP) vs the RWI in restoration of hearing in patients with COM. Patients and methods: Thirty-eight patients with bilateral moderate to severe mixed or conductive hearing loss from COM without cholesteatoma and bilateral ossicular chain erosion (footplate residual) were alternately assigned to a titanium-TORP (T-TORP) and to RWI with the FMT of the Medel Vibrant Soundbridge (MVBS) located onto the RW niche. The therapeutic efficiency, preoperative vs postoperative air-conduction gain and speech recognition were investigated for the two groups and statistically analyzed at 36 months postoperatively. The following postoperative anatomic conditions were also evaluated for the two groups: 1) recurrence of infection, 2) retraction pocket, 3) extrusion rate, and 4) displacement of the prosthesis. Results: Good functional results and stability at 36 months were obtained with both procedures. The extrusion rates for T-TORP were low. So far no extrusion has been observed for RWI. Hearing results were statistically much better for RWI vs T-TORP for all investigated parameters.
