Comparative study of type I tympanoplasty with or without mastoidectomy in tubotympanic type of chronic suppurative otitis media patients

Abstract

Objectives: The aim is to compare the results of type I tympanoplasty alone and tympanoplasty with cortical mastoidectomy in safe chronic suppurative otitis media (CSOM) patients in terms of graft uptake, improvement in hearing and clinical improvement. Study Design: This was prospective study. Materials and Methods: Sixty cases of safe type of CSOM were included in the study. Type I tympanoplasty was done in thirty cases and tympanoplasty with cortical mastoidectomy was done in another thirty cases. Patients were followed up postoperatively at 3, 6, and 12 weeks for graft uptake and any complication. Pure-tone audiometry was done at 6th and 12th week postoperatively to note the hearing improvement. Results: Graft uptake was 76.67% in tympanoplasty alone group and 83.33% in tympanoplasty with cortical mastoidectomy group. In the present study, pre- and post-operative pure-tone average was compared and the statistical difference between tympanoplasty group and tympanoplasty combined with cortical mastoidectomy group was not statistically significant. Recurrence of discharge was seen in 6 cases of tympanoplasty alone group. Although tympanoplasty combined with cortical mastoidectomy is better in hearing yield, graft acceptance rate, and clinical benefit, but the difference in two groups is statistically insignificant. Conclusion: Hearing outcome, graft acceptance rate, and clinical benefit were statistically unequalled in two groups. Tympanoplasty combined with cortical mastoidectomy will not give an additional advantage in terms of hearing gain, disease clearance, and graft uptake.
