We aim to investigate hearing sensitivity and wideband tympanometry results in bone cement ossiculoplasty cases in present study.
A prospective study.
Ossiculoplasty patients were grouped according to the anatomical location of bone cement application by surgery note. Ossiculoplasty and tympanoplasty patients were retrospectively invited to the clinic and evaluated. 30 bone cement ossiculoplasty cases as well as 30 Type I tympanoplasty cases (intact ossicular chain) and 30 healthy controls were included in the study and Wideband Tympanometry was performed. Tympanometric peak pressure, equivalent middle ear volume, static admittance, tympanogram width, resonance frequency, average wideband tympanometry and absorbance measurements were analyzed.
A statistically significant improvement was observed in the hearing levels of all ossiculoplasty and type I tympanoplasty patients (p < 0.05). Bone cement ossiculoplasty groups demonstrated the remarkable differences than the type I tympanoplasty and control group in Wideband Tympanometry test parameters. In some parameters, malleus-stapes and manubriostapedioplasty groups demonstrated similarities to Type I tympanoplasty and control groups.
Bone cement is an effective application for ossiculoplasty. Wideband tympanometry is a promising method for the evaluation of the middle ear dynamics.
本研究旨在探讨骨水泥耳骨成形术病例的听力敏感度和宽频鼓室图结果。
前瞻性研究。
根据手术记录中骨水泥应用的解剖位置将耳骨成形术患者分组。回顾性邀请耳骨成形术和鼓室成形术患者到诊所进行评估。研究纳入 30 例骨水泥耳骨成形术病例，30 例 I 型鼓室成形术（完整听骨链）和 30 例健康对照，并进行宽频鼓室图测试。分析鼓室图峰压、等效中耳容积、静态导抗、鼓室图宽度、共振频率、平均宽频鼓室图和吸光度测量值。
所有耳骨成形术和 I 型鼓室成形术患者的听力水平均有统计学显著改善（p<0.05）。骨水泥耳骨成形术组在宽频鼓室图测试参数方面与 I 型鼓室成形术组和对照组存在显著差异。在某些参数方面，锤骨-砧骨成形术和胸骨-砧骨成形术组与 I 型鼓室成形术组和对照组相似。
骨水泥是一种有效的耳骨成形术应用方法。宽频鼓室图是评估中耳动力学的一种有前途的方法。
