Tympanoplasty Outcomes in Dry and Wet Ears

Abstract

 Introduction: Chronic suppurative otitis media is a major public health problem in children and 
adults. Tympanoplasty is a surgical procedure which aims to prevent recurrent otorrhea and 
restore hearing ability.
 Objective: To compare the graft uptake and the hearing outcome of tympanoplasty in non 
cholesteatomatous chronic otitis media between wet and totally dry ears.
 Methods: A total of 108 wet ears (with mucoid discharge) and 232 dry ears (at least 3 months 
before surgery) with chronic suppurativeotitis media were operated on by myringoplasty 
between 2000 and 2014. Postoperative graft uptake and hearing gain rates were compared 
between both groups.
 Results: Cartilage was used in 100% of wet ears and 35% of dry ears. In the other cases, 
temporalis fascia was the chosen graft. Anatomical success rate was 88% for the wet ear group 
and 87.5% for the dry ear group. The hearing gain rate was 62%% for the wet ear group and 
56% for the dry ear group. Differences were found to be statistically non significant for both 
graft intake (p=0.9) and hearing gain (p=0.29). In the wet ear group, only age <40 years was 
found to be a predictive factor of audio logical success in tympanoplasty (p=0.001).
 Conclusion: The success of myringoplasty is not adversely affected by the presence of mucoid 
ear discharge at time of surgery, and outcomes are comparable to those of the operation done 
for dry ears.
