The clients were randomly divided into two groups case and control, each with 30 individuals. After tympanoplasty the case group took oral vitamin C for one month, but the control group received placebo. The patients were then followed up for three years. Preoperative and postoperative condition of tympanum and audiometry results in the two groups were compared (2.5 months and 3 years later). The obtained data were analysed by means of SPSS software, using paired t-test at the significant level P≤0.05. Results: Respectively, 86.7 and 83.3% of the case group and control group had successful tympanoplasty. vitamin C did not have any effect on the success of tympanoplasty in the case group compared with the control group.
