Evaluation of Factors affecting Surgical Outcome of Tympanoplasty

Tympanoplasty is a standard procedure to repair tympanic membrane perforation. The aim of this study is to evaluate the results of tympanoplasty (hearing improvement and tympanic membrane closure rate) in patients suffering from chronic perforation of the tympanic membrane by considering the prognostic factors.
In a prospective study, based on the results of tympanoplasty with temporal graft fascia in 60 patients in the ENT department of the Medical Science University of Tabriz, we evaluated prognostic factors, such as age, sex, smoking, size, and site of perforation, for the outcome of this surgery.
The rate of surgical success- integration of the graft- was 93.3%. Improvement of hearing, as demonstrated through audiometry, occurred in 93% of cases. We did not find any factors to be statistically significant to affect surgical outcome.
Even by considering the influence of different factors on the results of a tympanoplasty operation, according to the statistical results of this study, there is not a significant difference in the results of the operation, neither in the health of the tympanic membrane after surgery nor in hearing development.
