Abstract

INTRODUCTION: Myringoplasty is repair of the perforation of tympanic membrane when middle ear space, its mucosa and ossicle are free of disease. Myringoplasty is commonly done under microscopy; Major disadvantage of operating microscope is that it provides a magnified image along a straight line. Now a day’s Endoscope is widely used to perform various surgeries and very useful while operating in cavities. Therefore in the present study we correlate the outcome of myringoplasty by microscopic method and endoscopic method. AIM AND OBJECTIVES: To compare the percentage of graft uptake and improvement in A-B gap between microscopic and endoscopic group. MATERIALS AND METHODOLOGY: The present study was conducted in department of otolaryngology in Madurai medical college. A total of 40 patients were selected having central perforation of tympanic membrane. These 40 patients were divided into two equal groups of 20 patients each. All the patients underwent myringoplasty under local anesthesia. In the first group, endoscope was used and in the second group microscope was used to do myringoplasty. The graft uptake was assessed and postoperative pure tone audiograms were compared with preoperative pure tone audiogram. RESULTS: At end of 6 month post op period endoscopic group, out of 20 cases, 85% graft uptake. Microscopic group 80% graft uptake. Student’s t- test (P value 0.915) shows there is no significant difference in graft uptake in both group. Hearing improvements are similar in both groups. Student's “t” test was used for statistical analysis for comparing the results (gain in A-B gap) of two groups, P value was 0.514. Hence there is no significant difference in the gain in A-B gap between the two groups. CONCLUSION: The present study, graft uptake rate in endoscopic and microscopic myringoplasty are similar, but in terms of minimal invasive surgery, proximity vision provided, wide angle view, visualize of the deep recess and hidden areas of middle ear in single operating field, postoperative recovery, less operative time, Endoscopic method produced superior results and overcomes the disadvantage of microscope.
