Tympanoplasty, Graft, Middle ear, Hearing impairment


Background: Many factors which influence the success rate of tympanic membrane closure, including age of the patient, size of the perforation, duration of the ear discharge, the presence or absence of infective discharge at the time of surgery. Aim was to find the effect of this discharge from the ear on the success of tympanoplasty.  

Methods: This is prospective study which was conducted on 100 cases with 50 patients each in dry and wet ear group. The study was conducted on patients of age 6 years to 60 years and of either sex presenting with chronic otitis media.   

Results: Ear discharge for less than 10 years, 78% in dry ear group and 81% in wet ear group. Around 64% had hearing impairment for<5 years in dry ear group and 60% in wet ear group. The size of perforation in dry ear group, medium size perforation was found predominant 46%, large in 42% and small in 12% patients. In wet ear group 46% patients had medium, 16% patients small and 38% patient’s large perforation. Hearing improvement seen in 35 (70%) cases and worsening in 3 (6%) cases in dry ear group and 38 (76%) hearing improvement, 3 (6%) worsening in wet ear group.

Conclusions: Graft failure was 4(8%) in dry ear and 5(10%) in wet ear. Hearing worsened in 6% cases in dry and wet ear group both. No other complications were seen in patients during follow up.
