Numerous studies have been conducted on the effect of the stapes superstructure after ossicular chain reconstruction, but the findings are not uniform.
To compare the hearing outcomes of ossicular chain reconstruction with partial ossicular replacement prosthesis (PORP) or total ossicular replacement prosthesis (TORP) under otoendoscopy.
The records of 111 patients diagnosed with chronic suppurative otitis media were retrospectively analyzed. These patients were divided into PORP group ( = 57) and TORP group ( = 54). They were further subdivided into subgroups PORP-a (with a malleus handle) and PORP-b (without a malleus handle), subgroups TORP-a and TORP-b. Pre- and postoperative audiometric results were analyzed.
The mean postoperative air conduction hearing thresholds improvement, mean air-bone gap improvement, and the success rate of reconstruction were significantly higher in the PORP group than in the TORP group ( < .05). The mean postoperative air conduction hearing thresholds improvement and the success rate of reconstruction were significantly higher in the PORP-a group than in the TORP-a group ( < .05); and similar results were concluded in comparison of the PORP-b group and the TORP-b group.
The stapes superstructure has an important positive effect on the postoperative outcome of endoscopic ossicular chain reconstruction.
关于听骨链重建后镫骨上部结构的影响已开展了大量研究，但结果并不一致。
在内耳镜下比较部分听骨赝复物（PORP）或全听骨赝复物（TORP）进行听骨链重建的听力结果。
回顾性分析111例诊断为慢性化脓性中耳炎患者的病历。这些患者分为PORP组（n = 57）和TORP组（n = 54）。他们又进一步细分为PORP - a亚组（有锤骨柄）和PORP - b亚组（无锤骨柄），TORP - a亚组和TORP - b亚组。分析术前和术后的听力测试结果。
PORP组术后平均气导听力阈值改善、平均气骨导间距改善及重建成功率均显著高于TORP组（P < 0.05）。PORP - a组术后平均气导听力阈值改善及重建成功率显著高于TORP - a组（P < 0.05）；PORP - b组和TORP - b组比较得出类似结果。
镫骨上部结构对内耳镜下听骨链重建的术后结果有重要的积极影响。
