To do so, we did a retrospective analysis of medical records of patients who underwent type-1 tympanoplasty in a tertiary university hospital. We evaluated the tympanic membrane closure and audiometric outcomes during the first year of follow-up, and compared the results according to some clinical and surgical factors. 130 operated ears were included in the study.
