A Comparative Study of Role of Cortical Mastoidectomy in Myringoplasty

Abstract

BACKGROUND: Chronic suppurative otitis media is an inflammatory process of mucoperiosteal lining of middle ear space and mastoid. Effect of mastoidectomy on patients without evidence of active infectious disease remains highly debated and unproven. In this study the role of cortical mastoidectomy in myringoplasty in patients of CSOM in dry as well as wet ears was evaluated. OBJECTIVE: To evaluate the efficacy and role of cortical mastoidectomy in patients with CSOM (safe type) in dry as well as wet ears. STUDY DESIGN: Prospective randomized. METHODS: Data was collected from the patients undergoing myringoplasty with or without cortical mastoidectomy. Study was carried out on a total of 80 patients undergoing the surgery. Study period was 18 months with 6 months of follow up. Outcome was evaluated in terms of graft rejection, lateralization and change in AB gap. STATISTICAL ANALYSIS: The statistical analysis was done using SPSS (Statistical Package for Social Sciences) Version 15.0 statistical Analysis Software. RESULTS: overall success rate was 77.5%. It was higher in dry ear (87.5%) as compared to wet ear (67.5%) and this difference was significant statistically. On evaluating odds of failure for wet ear, it was observed that group 1 had higher odds of failure for wet ear as compared to that of group 2. CONCLUSION: In both myringoplasty alone or with cortical mastoidectomy, failure rates were higher in wet as compared to dry ears, however odds of failure in wet cases were much higher in myringoplasty alone group as compared to myringoplasty with cortical mastoidectomy.

Cortical Mastoidectomy with Tympanoplasty in the Management of Chronic Mucosal Otitis Media

“…Reperforation due to infection noticed only in 2 patients (6%), within 4 months of observational period. 22 In our study, graft failure occurred in 07 patients (14% In our study hearing gain was found in 34 patients (68%). No hearing improvement was found in 16 patients (32%).…”

The Outcome of Myringoplasty with d without Cortical Mastoidectomy Comparative Study between Elastic Nail Versus Plates and Screws in the Treatment of Diaphyseal Both Bone Forearm Fracture in Children

“…The mean pre-and postoperative pure tone average was 42.4 ± 10.53 dB and 32.8/13.02 dB (inpatient underwent myringoplasty alone) with a mean hearing gain of 9.5 ± 11.33 dB, no statistical significance between two groups 9 . Kawatra et alreported mean change in the air-bone gap was slightly higher in the group of myringoplasty with cortical mastoidectomy 10.13 ± 6.65 as compared to group II of myringoplasty alone 9.75 ± 5.99 15 .…”

Factors influencing decision making among ENT surgeons on performance of cortical mastoidectomy for CSOM-tubotympanic disease in quiescent/active stage: an opinion based study

“…When Kawatra et al compared outcome of myringoplasty and myringoplasty with cortical mastoidectomy in dry and wet ears, overall failure rate was significantly higher in wet type as compared to dry type, however, odds of failure in wet cases were much higher in myringoplasty alone group as compared to myringoplasty with cortical mastoidectomy. 19 Hence they had concluded that this proportional difference in graft take up rate in both dry and wet types indicated the results to be favouring cortical mastoidectomy especially in wet cases where it reduced the odds of failure substantially.…”
