Evaluation of outcomes of tympanoplasties with and without cortical mastoidectomy

Abstract

Context: Even today well-trained and experienced otologists remain divided as to the importance of combining mastoidectomy with tympanoplasty in the treatment of chronic non-cholesteatomatous otitis media. We performed a comparison of patients with postinfectious simple tympanic membrane perforations treated with tympanoplasty or with tympanoplasty combined with intact canal wall mastoidectomy, in terms of outcome. Aims: The aim of the study was to evaluate the outcomes of tympanoplasties with and without cortical mastoidectomy in terms of graft uptake rate and hearing improvement. Settings and Design: A combination of retrospective and prospective cohort study. Materials and Methods: A total of 65 patients undergoing tympanoplasty with or without cortical mastoidectomy were included in the study and were followed up for a period of one year for the graft uptake and hearing improvement. Statistical analysis used: Fisher's exact test and chi square test. Results: In our study, there was no significant difference in the graft uptake rate or the hearing improvement in both these groups. Conclusions: As per this study, it can be concluded that the addition of cortical mastoidectomy to type I tympanoplasty did not improve the graft uptake rate or the hearing improvement in cases of chronic suppurative otitis media tubotympanic disease.
