Objectives: To compare the results of tympanoplasty alone and tympanoplasty with cortical mastoidectomy in chronic suppurative otitis media (CSOM) patients with sclerotic bone in terms of graft uptake, perforation closure, improvement in hearing and disease eradication. Study Design: Retrospective study of patients at tertiary referral hospital. Method: 50 cases of non-cholesteatomatous chronic suppurative otitis media were selected. Tympanoplasty alone was done in 25 cases and tympanoplasty combined with cortical mastoidectomy was done in another 25 cases. Patients were reviewed postoperatively at 4, 8 and 12 weeks to inspect the operated ear for graft uptake or any complication. Pure tone audiometry(PTA) was done at 2 nd and 4 th month to evaluate the hearing improvement. Results: In our study, hearing gain in decibel ( dB ) in tympanoplasty group was 7.64 and in tympanoplasty combined with cortical mastoidectomy was 8.84. Graft uptake was 76% in tympanoplasty group and 88% in tympanoplasty combined with cortical mastoidectomy. Recurrence of discharge was seen in 2 cases of tympanoplasty. Though tympanoplasty combined with cortical mastoidectomy is better in hearing improvement, graft uptake and clinical improvement but the difference in 2 groups is statistically insignificant. Conclusion: Hearing improvement, graft uptake and clinical improvement were statistically incomparable in 2 groups. Combining cortical mastoidectomy with tympanoplasty will not give additional benefits in terms of hearing gain, disease clearance and graft uptake.
