Backgrounds: Otosclerosis is the cause of between 5% and 9% of all deafness cases and between 18% and 22% of conductive hearing loss cases. Neurosensory deafness develops in 30% of patients with otosclerosis.Aims/Objectives: The aim was to seek a correlation that would reflect the dependence of the results of middle ear surgery on the type of abnormalities atypical of otosclerosis but found during the stapedotomy surgery.Materials and Methods: The analysis included 140 patients who underwent surgery for otosclerosis. The hearing of all patients was assessed using an audiometric test.Results: In the assessment of changes in the mean bone conduction values, statistically significant differences between the reference group and the subgroup of patients on whom a myringoplasty was performed, as well as in patients with adhesions present in the middle ear spaces, were found only for the 500 Hz frequency.Conclusion and Significance: The removal of abnormalities, such as the loss of the eardrum (iatrogenic), changes to the lining and adhesions other than those typical of otosclerosis, restores middle ear mechanics after a stapedotomy on the inner ear and leads to a measurable improvement in mean bone conduction values.
