42 Is Cortical Mastoidectomy Justified in Tubotympanic Chronic Otitis Media

Abstract

Objectives: To compare the graft uptake rates and hearing outcomes in cases of tubotympanic chronic otitis media undergoing Tympanoplasty with and without Cortical mastoidectomy.Materials & Methods: It was a prospective study carried out over the period 1 year from 2012-13 with a sample size was 50 patients. Patients were randomised into Group A(tympanoplasty group) or group B(Tympanoplasty with cortical mastoidectomy group). Independent two sample T test was used to compare post operative graft uptake rates and hearing outcomes in the two groups.Results: Post operative graft uptake rates at the end of 6 months and mean hearing gain were found comparable in both groups (p>0.05).Conclusion: Tympanoplasty alone is sufficient in patients with tubotympanic type of chronic otitis media, as the results of graft uptake and hearing improvement show no significant difference between the tympanoplasty and cortical mastoidectomy group.
