Different types of prosthesis are available for stapes replacement. Because there has been no published report on the efficacy of the titanium soft-clip vs the fluoroplastic Causse loop Teflon piston, we compared short-term hearing results of both types of prosthesis in patients who underwent stapedotomy due to otosclerosis.
A total of 57 ears were included in the soft-clip group and 63 ears were included in the Teflon-piston group. Pre-operative and post-operative air conduction, bone conduction, air-bone gaps, speech discrimination score, and speech reception thresholds were analyzed.
Post-operative speech reception threshold gains did not differ significantly between the two groups (P=0.919). However, better post-operative air-bone gap improvement at low frequencies was observed in the Teflon-piston group over the short-term follow-up (at frequencies of 0.25 and 0.50 kHz; P=0.007 and P=0.001, respectively).
Similar post-operative hearing results were observed in the two groups in the short-term.
有不同类型的假体可用于镫骨置换。由于尚未有关于钛质软夹与氟塑料考斯环特氟隆活塞疗效的公开报告，我们比较了因耳硬化症接受镫骨切除术患者中这两种假体的短期听力结果。
软夹组纳入57耳，特氟隆活塞组纳入63耳。分析术前和术后的气导、骨导、气骨导间距、言语辨别得分和言语接受阈。
两组术后言语接受阈增益无显著差异（P = 0.919）。然而，在短期随访中，特氟隆活塞组在低频处的术后气骨导间距改善更好（在0.25和0.50千赫频率处；P分别为0.007和0.001）。
短期内两组观察到相似的术后听力结果。
