Abstract

Introduction:
Tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .This paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.
 Materials and Methods:
Sixty referring patients to specialty and subspecialty clinics between the age 15 to 60 years-old were selected. All patients suffered from Chronic Otitis Media and they were categorized into two groups: a) those with wet ears and b) those with dry ears. Tympanoplasty surgery was performed through the use of embedding technique of temporalis fascia graft and in medial position (Medial Graft Technique). Finally, the data about the level of hearing improvement and the repair of tympanic membrane were analyzed.
 Results:
Although there was hearing improvement in both groups - with wet or dry ear - no statistically significant difference was observed between two groups. Following the surgery, tympanic membrane in two patients with wet ear and one with dry ear was not repaired, however according to the statistical analysis this difference was not significant.
 Conclusion: 
The results of this study showed that in contrast to the common perception that tympanoplasty results in the patients with wet ear is poorer than those with dry ear, there was little difference in the results of the operations performed on two groups.
