Predictive Value of Middle Ear Risk Index Score in the Outcome of Tympanomastoidectomy and Tympanoplasty

Abstract

Background and objectives: Chronic otitis media (COM) is an otological challenge especially prevalent in developing countries like India for which tympanoplasty with or without mastoidectomy is the treatment of choice. In this study, we aim to assess the predictive value of the middle ear risk index (MERI) score in the outcome of tympanoplasty. Subjects and methods: Fifty patients who underwent surgery at Lok Nayak Hospital for chronic suppurative otitis media received preoperative MERI score assessments. They were subsequently followed, and their results were evaluated based on the MERI score. Results: There is a statistical significance concerning graft uptake and hearing gain based on the MERI score. As the MERI score increased, the chances of graft uptake decreased, and the mean hearing gain also decreased accordingly. Conclusion: All patients undergoing surgery for COM should be assessed preoperatively for MERI score so that appropriate counselling and prognostication can be done about the chances of success of surgery.
