  • Background: To determine the prevalence of community-acquired methicillin-resistant S. aureus (CA-MRSA) and methicillin-sensitive S. aureus (MSSA) nasal abscesses in a lower socioeconomic status urban population over a 5-year period. Methods: A retrospective chart review of 29 consecutive patients with nasal abscess cultures performed in the otolaryngology clinic from 2007 to 2012. Results: Twenty-nine cases of nasal abscesses were identified. All cultures grew S. aureus; 34.5% were MSSA and 65.5% were CA-MRSA. Comparing CA-MRSA and MSSA, there was no statistically significant increase in prevalence of CA-MRSA over 5 years; and there was no statistical difference comparing gender, year, or age. There was a high rate of erythromycin resistance (15/19) and a low rate of sulfamethoxazole/trimethoprim (2/19) and clindamycin (1/19) resistance in the CA-MRSA cases. Conclusion: In this population, the proportion of CA-MRSA nasal abscesses is nearly twice that of MSSA nasal abscesses. The overall prevalence of CA-MRSA appears to be stable over the past 5 years. This may represent a stabilization of CA-MRSA colonization in this community. An awareness of the high proportion of CA-MRSA will allow for the appropriate selection of antibiotic therapy. © 2013 ARS-AAOA, LLC.
