- Abstract
Chronic otits media (COM) is surgically treatable disease which includes complete removal of disease and improving hearing via ossicular reconstruction. Therefore, thorough assessment of the disease, ossicles and various factors causing it plays a major role in surgical outcome prediction. MERI (Middle ear risk index) is one such tool being used worldwide. Our aim was to evaluate the surgical outcome of tympanomastoid surgery using MERI and find out correlation between them as well as categorize cases into their severity score in a developing country. Observational prospective study conducted in a tertiary care center. 200 patients were included. After complete history and examination, they were given MERI scores and prediction of surgical outcome was done. Postoperatively it was compared with the real outcome of the surgery. Out of 200 patients, 71.5% had mild, 15.5% had moderate and 13% had severe MERI scores preoperatively. There was a success rate of 88.5% in graft uptake and the mean score of hearing benefit (A-B gain) among patients was 8.75 ± 8.82 dB postoperatively. MERI may be used as a prognostic indicator for predicting surgical outcome. Based on the MERI score, chances of surgical success and hearing benefit can be explained to the patient with certain limitations.
