Effectiveness of Myringoplasty in Patients with Eosinophilic Otitis Media

Objective: To determine whether myringoplasty can be an effective tool to control eosinophilic otitis media and improve hearing. Methods: Severity scores for patients with eosinophilic otitis media with or without myringo-plasty were retrospectively analyzed. Surgical outcomes were assessed and compared to those of patients with control: chronic otitis media with tympanic membrane perforation. Results: The average eosinophilic otitis media severity score for the patients with myringoplasty was significantly lower after than before surgery (P = 0.004), although the score for the group without myringoplasty remained stable during the study period. The success rate for graft uptake was 87.5%, and a statistically significant improvement was observed in the postoperative air conduction hearing level within the speech range (mean +/- standard deviation; 41.5 +/- 12.3 to 34.6 +/- 9.22 dB; P = 0.0026) for patients with eosinophilic otitis media. Conclusion: Myringoplasty contributed to decreased postoperative eosinophilic otitis media severity scores and should be considered to protect the patients from recurrent bacterial infections and pathogenic antigen parasitism in the middle ear.
