Comparative Evaluation of Tympanoplasty with or Without Mastoidectomy in Treatment of Chronic Suppurative Otitis Media Tubotympanic Type.

To study the role of tympanoplasty alone and tympanoplasty done along with cortical mastoidectomy in CSOM in term of graft uptake, improvement of hearing and removal of disease. This is retrospective study of patient at tertiary referral centre, conducted in between October 2015 and October 2016, study was done on 40 patients of either sex in the age group 20-50 years. Tympanoplasty alone was done in 20 cases and tympanoplasty along with cortical mastoidectomy was done in rest 20 cases. Patient were reviewed post operatively on 2, 4, 8 and 16 weeks to inspect post operative graft uptake and PTA was done at fourth month to evaluate hearing improvement. Hearing improvement was compared in both the groups in tympanoplasty group was 9.41 and in tympanoplasty combined with cortical mastoidectomy was 12.05. Graft uptake was 80% in tympanoplasty group and 95% in tympanoplasty combined with cortical mastoidectomy. Recurrence of discharge was seen in 4 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. Results of tympanoplasty alone and tympanoplasty along with cortical mastoidectomy in terms of hearing gain and graft uptake were statistically insignificant.
