Aim: To assess the usefulness of the Middle Ear Risk Index (MERI) in adequately predicting the success of tympanoplasty in the pediatric population.Methods: Retrospective study of children (age under 18 years old) who underwent tympanoplasty between 2014 and 2021. Demographic data, contralateral ear status, surgical technique, type of graft, pre and postoperative audiometric data and MERI score were collected.
Results: Forty-seven children were evaluated (total of 58 ears), with an average age of 13±2.71 years. Cases with MERI lower than three had an odd ratio value of 0.35, demonstrating that this score is a protective factor for favorable postoperative results. In cases compatible with severe disease (MERI > 7) there was a chance about 17 times higher of having an unfavorable outcome in the postoperative period. Both these results were statistically significant (p<0.05).
Conclusion: This study concludes that the MERI can be a useful tool in the preoperative evaluation in order to assess the probability of success of pediatric tympanoplasty.
