Qualitative results:
In the control group, the tympanic membrane was observed to be intact in 10 of the 16 ears, while it was not observed in 6. Inflamed cells were observed in the tympanic membrane of 1 ear and the tympanic bulla mucosa of 2 ears. A small number of inflamed cells were present in the tympanic membrane while a significant amount of inflamed cells were observed in the tympanic bulla mucosa, and it was noted that almost all of the inflamed cells consisted of polymorphonuclear leukocytes. Cholesteatoma was seen in 8 ears. In 3 ears fibrinous-proteinosis material was observed.
In the experiment group the tympanic membrane was observed to be intact in 8 of the 16 ears, and it was not observed in 8. Cholesteatoma was seen in 7 of the ears (figure 1-2). Obvious inflammation and fibrosis were not observed in the tympanic membrane and tympanic bulla mucosa.
No statistically significant difference between the two groups regarding the prevalence of cholesteatoma and the presence of fibrosis was observed (p>0.05). Meanwhile in the microscopic histopathological evaluation the prevalence of cholesteatoma and fibrosis were observed to be lower in the experiment group.
