Abstract：
OBJECTIVE: The outcome of cartilage interposition ossiculoplasty was assessed in cases of incus necrosis after posterior malleus repositioning in the plane of the stapes, in terms of hearing gain after ossicular reconstruction.
METHODS: A retrospective observational study was conducted of 30 patients admitted to an Ain Shams University hospital from March 2021 to September 2021. All patients with ossicular disruption due to chronic suppurative otitis media and hearing loss of more than 40 dB were included in the study. Pure tone audiometry was conducted for each patient after three months, six months and one year post operation.
RESULTS: The audiogram showed a post-operative air-bone gap of 20 dB or less in 83.33 per cent of patients (n = 25) at three months post-operatively and in 80 per cent of patients after six months; after one year, the results remained the same.
CONCLUSIONS: The use of cartilage interposition after malleus posterior mobilisation represents an excellent partial ossicular replacement technique.

摘要：
目的：在骨骨平面内重新定位后，在砧骨坏死的情况下评估软骨插入骨成形术的结果，听骨重建后的听力增益。
方法：对2021年3月至2021年9月AinShams大学医院收治的30名患者进行了回顾性观察性研究。所有因慢性化脓性中耳炎而听骨破裂且听力损失超过40dB的患者均纳入研究。3个月后对每位患者进行纯音测听,运营后六个月零一年。
结果：听力图显示，83.33%的患者(n=25)术后3个月和80%的患者术后骨气间隙为20分贝或更小。结果保持不变。
结论：锤骨后移动后使用软骨插入是一种出色的部分听骨置换技术。
