Objective:
The aim of this study was to examine the role of the prognostic factors and middle ear risk index on the success of tympanoplasty.
Study Design:
Case series.
Subjects And Methods:
The charts of 231 patients who underwent tympanoplasty operations between 2002 and 2007 were reviewed. Prognostic factors such as age, sex, presence of systemic diseases, location and size of perforation, duration of dry period, presence of myringosclerosis, presence of septal and conchal pathology, operation type, and status of the opposite ear and middle ear risk index were investigated.
Results:
The overall success rate was 74.4%. Multivariate analysis was carried out on significant prognostic factors to obtain independent variables and yielded the following results (95% CI): size of the perforation (<50%) (OR:8.11), healthy opposite ear (OR:5.64), more than 3 months dry period (OR:2.21), absence of myringosclerosis (OR:4.01) and low middle ear risk index (OR:87.1).
Conclusion:
Size of the perforation(<50%), healthy opposite ear, absence of myringosclerosis, more than 3 months dry period, and low middle ear risk index were found to be significant independent prognostic factors.
