Abstract
calculated. The patients were categorised into those with mild, moderate and severe MERI. The hearing benefit was calculated from the pre and post operative air-bone gap. The graft status was assessed. The relation between MERI score and graft status and between MERI score and hearing benefit was assessed by T test and Chi-Square test respectively. RESULTS: The overall graft uptake was 76%. Patients with a high MERI score have lower rate of graft uptake which is statistically significant with a P value of 0.031. Also, patients with mild MERI had greater hearing benefit and those with severe MERI had lesser hearing benefit postoperatively which is statistically significant with a P value of 0.041. The mean hearing benefit was 9.90 dB. CONCLUSION: MERI score is a prognostic tool to predict the outcome of tympanoplasty. It has an inverse relation with graft uptake and hearing benefit. Based on MERI score, the chances for surgical success and hearing benefit should be explained to the patient.
