A Comparative Evaluation between Tympanoplasty with or Without Cortical Mastoidectomy

Aims and Objectives: To compare the results of tympanoplasty alone and tympanoplasty with cortical mastoidectomy in chronic suppurative otitis media (CSOM) patients in terms of graft uptake, perforation closureand improvement in hearing. Method: The study enrolling total 60 patients of either sex, age between 15 to > 45 years and were divided in two equal groups. Group A operated by type 1 tympanoplasty alone and group B operated by type 1 tympanoplasty with cortical mastoidectomy.The graft uptake rate and hearing improvement was compared between these two groups based on follow up and repeat audiogram on 12 th postoperative week. Results: In the presentstudy, majority of patients were in the age group of 26-35 years with female predominant by male to female ratio of 1: 3.6.Graft uptake success rate were more in group B (93.3 %)than in group A(90 %).Three months after the surgery, 22 (73.33%) patients showed hearing improvement in group A and 25 (83.3%) patients in group B which was not statistically significant. Conclusion: The graft uptake and hearing improvement were clinically better in group B but difference in two groups was statistically insignificant. Combining cortical mastoidectomy with tympanoplasty does not give additional benefit in terms of hearing improvement or graft uptake but ABC closure after 3 months of surgery was significantly better in group B.
