The mean preoperative PTA average was 44.34 dB (SD 8.01 dB) for patient with mild MERI, 44.75 dB (SD 5.87 dB) for patient with moderate MERI, and 54.9 dB (SD 14.05 dB) for patient with severe MERI and the mean preoperative A-B gap was 37.36 dB (SD 5.73 dB). Post operatively for mild MERI mean hearing gain is 12-14dB, for moderate MERI mean hearing gain is 10-13dB and for severe MERI mean hearing gain is 10-13dB and post operative mean A-B gap was improved by 10-11dB. There is a statistically significant hearing improvement in A-B gap with different types of MERI.</p><p><strong>Conclusion: </strong>MERI scoring is useful for predicating the outcome of hearing after tympanoplasty.</p><p><strong>JNGMC</strong> Vol. 13 No. 2 December 2015, Page: 6-9</p>}, number={2}, journal={Journal of Nepalgunj Medical College}, author={Sharma, Anshu and Saxena, R.
