OUTCOME OF MYRINGOPLASTY IN ACTIVE AND INACTIVE EARS IN TERMS OF GRAFT UPTAKE

Abstract

Objectives: To determine whether the presence of aural discharge at the time of myringoplasty adversely affects successful graft uptake.

Materials and methods: This prospective, comparative interventional study was done at department of Otorhinolaryngology – Head & Neck Surgery, National Academy of Medical Sciences, Bir Hospital, Kathmandu between May 2016 to May 2017 including 100 patients with chronic otitis media – mucosal type with or without mucoid ear discharge (50 in each group).The patients who presented with mucoid discharge (wet) or edematous middle ear mucosa were categorized into active ears(group –A) and those with no discharge and dry at least for 3 months categorized into inactive ears( group- B). All the patients were treated with (undergone)myringoplasty under local anaesthesia through permeatal approach. Otoscopic examination was carried out to assess the uptake of the graft. Success of myringoplasty was regarded if there was no residual perforation and there was no significant retraction of the graft. Successful uptake of the graft in both active and inactive ears were compared statistically.

Results: Successful graft uptake was noticed in 74% patients of the active ear(wet) group and in 78% patients of the inactive ear(dry) group, and the difference was not found to be statistically significant (p value 0.81).

Conclusion: Mucoid ear discharge is not a reason to postpone myringoplasty, as it has no adverse effect on the outcome of the operation in regards to graft uptake.
