Abstract

Objective

To report a rare case of a marked improvement in bone conduction (BC) thresholds following the reinforcement of the oval window (OW) prior to the implantation of a total ossicular replacement prosthesis (TORP).

Methods

A clinical case involving OW reinforcement followed by TORP implantation was retrospectively analyzed, with pre- and postoperative pure tone averages (PTA) at four frequencies for BC and air conduction (AC) measured and compared.

Results

The bone conduction PTA across four frequencies improved significantly from 62 dB preoperatively to 16 dB postoperatively in the patient's only hearing ear, which had previously experienced acute hearing loss and was affected by cholesteatoma. Concurrently, the AC PTA also improved, decreasing from 76 dB to 33 dB.

Conclusion

In patients presenting with benign middle ear lesions that result in destruction of the stapes footplate and concomitant reduction in BC, it is essential to first exclude sensorineural etiologies, including labyrinthitis and auditory neuropathy. Subsequently, consideration should be given to reinforcing the OW utilizing autologous cartilage.

卵圆窗加固后TORP植入后骨传导显著增强：1例报告及综合叙述回顾

目的报道一例在全听骨置换术（TORP）植入前卵圆窗（OW）加固后骨传导（BC）阈值显著改善的罕见病例。方法回顾性分析1例OW强化后植入TORP的临床资料，比较术前和术后4个频率的BC和空气传导（AC）的纯音平均值（PTA）。结果术前急性听力损失、胆脂瘤患者的骨传导PTA在4个频率上由术前62 dB显著改善至术后16 dB。同时，交流PTA也有所改善，从76 dB下降到33 dB。结论中耳良性病变导致镫骨足板破坏并伴有BC减少的患者，首先应排除感觉神经病因，包括迷路炎和听神经病变。随后，应考虑利用自体软骨加强OW。
