SURGICAL OUTCOME OF MYRINGOPLASTY WITH AND WITHOUT CORTICAL MASTOIDECTOMY IN CHRONIC OTITIS MEDIA MUCOSAL INACTIVE TYPE

Abstract

Background: Chronic otitis media is usually complicated due to perforation of tympanic membrane and ultimately leading to hearing loss. The objective of this study was to compare the results of myringoplasty alone with myringoplasty with cortical mastoidectomy in COM (Chronic Otitis Media) mucosal inactive type in terms of graft uptake.

Methods: This was a descriptive, prospective, qualitative type of study. A total of thirty patients of COM mucosal inactive type were included in the study of which 15 patients were selected alternatively for myringoplasty alone while another 15 patients were selected for myringoplasty with cortical mastoidectomy. Pure tone audiometry was done within 1 week prior to surgery. Graft uptake was assessed after 6 weeks and results were compared within and between the groups using Chi-square test.

Results: Graft uptake rate of myringoplasty alone and myringoplasty with cortical mastoidectomy done using temporalis fascia graft and underlay technique was same 86.66% (n=26) and failure rate was 13.33% (n=4).The graft take was higher 88.9%(n=8) in small perforation worsened in medium (85 %) and then in subtotal perforation (79%). Graft uptake rate was highest in central perforation (86.9%) followed by posterior perforation (84.6%) and least in anterior perforation (77.7%). Mean age of presentation was 27.7 years, ranging from 15 to 60 years. Most common approach was permeatal in myringoplasty and postaural in case of myringoplasty with cortical mastoidectomy.

Conclusions: The graft uptake rate myringoplasty alone are comparable to those of myringoplasty with cortical mastoidectomy. The choice of surgery is based on surgeon’s preference.
