Assessment of the outcome of myringoplasty with cortical mastoidectomy in dry and wet mucosal type of chronic otitis media
Keywords:Cortical mastoidectomy, Chronic otitis media, Myringoplasty
Background: Chronic otitis media (COM) is an inflammatory process in the middle ear space that results in long-term changes in the tympanic membrane including atelectasis, dimeric-membrane formation, perforation, tympanosclerosis, retraction pocket or cholesteatoma. COM can be classified into healed, inactive (mucosal or squamosal), active (mucosal or squamosal). Myringoplasty is tympanoplasty without ossicular reconstruction. Cortical mastoidectomy is usually accompanied by tympanoplasty. Aim was to assess and compare the efficacy of myringoplasty with cortical mastoidectomy in dry and wet mucosal type of COM, in terms of graft uptake and hearing improvement.
Methods: A prospective study, where 30 patients each of wet and dry mucosal-type COM were included. Patients underwent myringoplasty with cortical mastoidectomy. All were followed up for 6 months, both the groups were statistically compared.
Results: In our study, mean age of patients in group A (wet COM) was 34.13 years and group B (dry COM) was 33.36 years. Group A had success rate of 90% and group B had success rate of 86.6%. There was no statistical significance (p value- 0.53) on comparing both groups with respect to graft uptake. There was significant hearing improvement post-operatively in both the groups (p<0.05). However, there was no significant difference between the groups (p value- 0.66). This shows that presence of discharge at the time of surgery does not interfere with the results of cortical mastoidectomy with myringoplasty.
Conclusions: We conclude that, there is good outcome in both wet and dry COM following myringoplasty with cortical mastoidectomy with respect to graft uptake and hearing improvement.
