Objective: We aim to investigate hearing sensitivity and wideband tympanometry results in bone cement ossiculoplasty cases in present study. Study design: A prospective study. Setting: 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. Results: 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. Conclusion: Bone cement is an effective application for ossiculoplasty. Wideband tympanometry is a promising method for the evaluation of the middle ear dynamics.
