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 6 weeks dry before surgery) with mucosal chronic otitis media were operated on by endoscopic myringoplasty by transcanal approach. Graft uptake and hearing gain rates 3 months 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.
本研究的目的是比较内镜下鼓膜成形术后活动性和非活动性黏膜慢性中耳炎患者的移植物摄取情况及听力改善情况。这是一项于2014年2月至2015年8月在一所政府医学院及医院进行的前瞻性研究。共有40例有黏液样分泌物的活动性（湿性）耳和40例有黏膜慢性中耳炎的非活动性（干性）耳（术前至少6周干燥）接受了经耳道入路的内镜下鼓膜成形术。比较两组术后3个月的移植物摄取率和听力增益率。采用经耳道入路使用颞筋膜移植物进行内镜下鼓膜成形术。活动性耳组的移植物成活率为77.5%，非活动性耳组为85%。非活动性耳组的听力增益率为82.5%，活动性耳组为72.5%。发现移植物摄取和听力增益的差异均无统计学意义。内镜下鼓膜成形术的成功不受手术时黏液样耳分泌物的不利影响，其结果与非活动性耳手术的结果相当。
