Objectives/Hypothesis:
The prevalence of methicillin-resistant Staphylococcus aureus (MRSA)-infected chronic otitis media (COM) has been increasing, but to date, there has been no consensus on surgical treatment. Although there is a report that mastoidectomy is essential in treating MRSA-infected COM, in our experience, we found that tympanoplasty without mastoidectomy was sufficient. In this study, we evaluated the efficacy of tympanoplasty without mastoidectomy on MRSA-infected COM.
Study Design:
Retrospective case-control study.
Methods:
Forty ears with MRSA-infected COM that underwent tympanoplasty without mastoidectomy were identified at a tertiary referral center from February 2006 to September 2011. Each case had two controls matched. Hearing results and postoperative complication were examined to evaluate the efficacy of tympanoplasty. The preoperative and postoperative pure tone audiometry was checked.
Results:
In the MRSA group and control group, 5 out of 40 ears (12.5%) and 8 out of 80 ears (10%) showed postoperative complications, respectively. The hearing success rate was 95.8% (23/24) in the MRSA group and 91.7% (44/48) in the control group. In the MRSA group, the average air-bone gap was 20 dB preoperatively, and it improved to 14 dB postoperatively. In the control group, the average air-bone gap was 19 dB preoperatively, and it improved to 13 dB postoperatively. There was no statistically significant difference between the MRSA and control groups.
Conclusions:
Tympanoplasty without mastoidectomy showed efficacy in MRSA-infected COM.
Insights
Tympanoplasty without mastoidectomy is effective for treating chronic otitis media caused by methicillin-resistant Staphylococcus aureus (MRSA). This surgical approach demonstrated comparable outcomes to standard treatments, with low complication rates and improved hearing.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Surgical Innovation
Background:
- Increasing prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in chronic otitis media (COM).
- Lack of consensus on optimal surgical management for MRSA-COM.
- Previous reports suggested mastoidectomy is essential, contrasting with our clinical observations.
Purpose of the Study:
- To evaluate the efficacy of tympanoplasty without mastoidectomy in treating MRSA-infected COM.
- To compare surgical outcomes between MRSA-infected COM and non-MRSA COM.
Main Methods:
- Retrospective case-control study design.
- Analysis of 40 ears with MRSA-COM undergoing tympanoplasty without mastoidectomy.
- Matched controls (80 ears) were used for comparison.
- Assessment of postoperative complications and pure tone audiometry for hearing outcomes.
Main Results:
- Low postoperative complication rates: 12.5% in the MRSA group vs. 10% in the control group.
- High hearing success rates: 95.8% in the MRSA group vs. 91.7% in the control group.
- Significant improvement in average air-bone gap in both groups (MRSA: 20 dB to 14 dB; Control: 19 dB to 13 dB) with no statistical difference.
Conclusions:
- Tympanoplasty without mastoidectomy is an effective surgical option for MRSA-infected COM.
- This approach yields comparable results to standard treatment for non-MRSA COM.
- The findings challenge the necessity of mastoidectomy in all MRSA-COM cases.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
