A comparative study on type I tympanoplasty with or without mastoidectomy in chronic otitis media-mucosal disease

Jaseetha S, Trisha Srivastava, Aditya Bhargava


Introduction: This comparative study evaluates the outcomes of type 1 tympanoplasty with or without mastoidectomy in chronic otitis media, mucosal disease in a tertiary care institute. Materials and methods: The study included 84 patients with mucosal type of ear disease in quiescent stage .42 of these patients underwent type 1 tympanoplasty alone [Group A] and 42 underwent type 1 tympanoplasty with mastoidectomy [Group B]. Patients were followed up in the outpatient clinic at one week, third week, three months, and six months after the surgery. At third and sixth month the patients underwent otoscopic evaluation and hearing assessment. Results: 19% of the patients who underwent Type I tympanoplasty had residual perforation at 6 months when compared with 14% of the patients of cortical mastoidectomy with Type I tympanoplasty which was statistically insignificant in this study. In group B out of 7 patients who had diseased mastoid status per operatively 4 had residual perforation which was significant [p<0.05]. Conclusion: In this study the comparison of results between groups A & B is statistically insignificant. Disease status of mastoid proved to be a significant factor for success of surgery. Belfast rule of thumb proved to be a better method to assess the post-operative hearing improvement subjectively.
