Effectiveness of Type I Tympanoplasty in Wet and Dry Ear in Safe Chronic Suppurative Otitis Media.

Abstract

The aims and objectives of the study were to compare the rate of graft uptake after type 1 tympanoplasty in wet and dry ears and also to compare the postoperative hearing improvement in wet and dry ears. It was a Non Randomized Experimental Study. This study was done in ENT OPD at Tertiary Health Care Institute of Central India. It was conducted from November 2012 to October 2014 on 86 patients having Safe Chronic Suppurative Otitis Media. The patients were divided into two groups as Dry ear group and Wet ear group. Dry ear group included patients whose ear was dry for at least 6weeks prior to the surgery. Wet ear group included patients who had minimal mucoid discharge in the middle ear which on culture and sensitivity showed no microorganisms. Type 1 Tympanoplasty was done in all patients. Results were analyzed statistically. Complete graft uptake was seen in 86.95% cases of Dry ear group and 80% of Wet ear group and the difference was statistically insignificant. Hearing improvement was achieved in 80% cases in dry group and 67.5% cases in wet group. The difference in hearing improvement in both groups was also statistically insignificant. So conclusion was drawn that, presence of minimal mucoid ear discharge at the time of surgery does not affect the success rate of Type 1 Tympanoplasty.
