Treatment of Buccal Staphylococcus Infection
For a buccal staph infection, incision and drainage is the primary treatment if an abscess is present, with antibiotic therapy added based on specific clinical features including facial location, systemic signs, or failure to respond to drainage alone.
Initial Assessment and Treatment Approach
The treatment strategy depends critically on whether the infection is purulent (abscess/drainable collection) versus non-purulent cellulitis:
If Abscess Present (Purulent Infection)
Incision and drainage is the cornerstone of therapy 1, 2, 3. For simple abscesses, drainage alone may be adequate, but antibiotics are specifically recommended for buccal infections because:
- Facial location is an area difficult to drain completely 2, 1
- The face represents a high-risk anatomic site requiring adjunctive antibiotic therapy 1
Antibiotic Selection
Given the rising prevalence of community-acquired MRSA (CA-MRSA), empirical coverage should account for this pathogen pending culture results:
Outpatient Oral Options for CA-MRSA Coverage:
- Clindamycin 300-450 mg three times daily (A-I evidence) 2
- TMP-SMX 1-2 double-strength tablets twice daily (A-II evidence) 1
- Doxycycline 100 mg twice daily (A-II evidence) 2
- Linezolid 600 mg twice daily (A-II evidence) 1
Clindamycin is particularly advantageous as it provides coverage for both CA-MRSA and β-hemolytic streptococci with a single agent 2. However, be aware that Clostridium difficile-associated disease may occur more frequently with clindamycin 2.
If dual coverage is needed (streptococci + MRSA), alternatives include TMP-SMX or doxycycline combined with a β-lactam like amoxicillin 1.
For Methicillin-Susceptible Staph aureus (MSSA)
Once susceptibilities confirm MSSA:
Duration of Therapy
5-10 days is recommended, individualized based on clinical response 1, 2, 1. The facial location and potential for complications may warrant treatment toward the longer end of this range.
When to Hospitalize
Consider inpatient management with IV antibiotics for:
- Severe or rapidly progressive infection
- Signs of systemic illness (fever, elevated WBC)
- Associated cellulitis extending beyond the immediate area
- Immunosuppression or significant comorbidities
- Lack of response to outpatient therapy 2, 1
IV Options for Hospitalized Patients:
- Vancomycin 15-20 mg/kg/dose every 8-12 hours (A-I) 2, 1
- Linezolid 600 mg IV twice daily (A-I) 2
- Daptomycin 4 mg/kg/dose IV once daily (A-I) 2, 1
- Clindamycin 600 mg IV three times daily (A-III) 2
Duration for complicated infections: 7-14 days 2, 1.
Critical Management Points
Culture and susceptibility testing is essential for buccal infections given the facial location and potential complications 1. Obtain cultures from any purulent drainage before initiating antibiotics.
Avoid rifampin as monotherapy or adjunctive therapy for skin and soft tissue infections 1, 2, 1.
Monitor closely for treatment failure, which would necessitate reassessment for deeper infection, abscess formation requiring drainage, or resistant organisms 2.
Pediatric Considerations
For children with buccal staph infections:
