Benefit of Tympanoplasty with or without Cortical Mastoidectomy in Active Mucosal Otitis Media – A Comparative Study

Abstract

Introduction: 
 Chronic otitis media (COM) is amongst the most common diseases treated by ENT surgeons in India. It has been advocated in lot of research articles that there is no significant difference in tympanoplasty done in active and inactive COM. The objective was to see if cortical mastoidectomy in cases of active mucosal COM, improves the success rate of tympanoplasty measured as per the following parameters: improvement in the hearing threshold by 15 dB, increased graft uptake and reduction in retraction of tympanic membrane in post operative period.
 Materials and Methods: 
 This study comprises of 120 patients coming to the ENT OPD from October 2016 to October 2017 with active mucosal COM with central perforation requiring tympanoplasty. These patients were randomly assigned to two groups: Group 1 of 60 subjects in which tympanoplasty without mastoidectomy was done, Group 2 of 60 subjects in which tympanoplasty with mastoidectomy was done. Patients were evaluated after a post operative period of 3 months.
 Results: 
 The Results were the hearing improvement was 73.33% in group 1 while 83.33% in group 2, graft uptake was 63.33% in group 1 and 80% in group 2, graft retraction was 33.33% and 23.33% in group 1 and group 2 respectively.
 Conclusion:
 There was statistically significant difference in results in group with and without mastoidectomy in active mucosal chronic otitis media with respect to graft uptake and improved hearing.
