Comparative Study of Outcome of Endoscopic Myringoplasty in Active and Inactive Mucosal Chronic Otitis Media Patients.

Abstract

The objective of this study was to compare graft uptake and hearing improvement in active and inactive mucosal chronic otitis media patients after endoscopic myringoplasty. This is prospective study conducted at a government medical college and hospital from February 2014 to August 2015. A total of 40 active (wet) ears with mucoid discharge and 40 inactive (dry) ears (at least 6weeks dry before surgery) with mucosal chronic otitis media were operated on by endoscopic myringoplasty by transcanal approach. Graft uptake and hearing gain rates 3months after surgery were compared for both groups. Endoscopic myringoplasty using temporal fascia graft via transcanal approach was used. The graft take rate was 77.5% for the active ear group and 85% for the inactive ear group. The hearing gain rate was 82.5% for the inactive ear group and 72.5% for the active ear group. Differences were found to be statistically insignificant for both graft uptake and hearing gain. The success of endoscopic myringoplasty is not adversely affected by the presence of mucoid ear discharge at the time of surgery, and outcomes are comparable to those of the operation done for inactive ear.
