Background:
Up to 20 percent of the general population is persistently colonized with Staphylococcus aureus, and 1 to 3 percent of the population is colonized with community-acquired methicillin-resistant S. aureus. Currently, the knowledge of methicillin-resistant Staphylococcus aureus carriage sites other than the nose, and their effect on surgical site infections in cosmetic surgery, is lacking.
Methods:
A comprehensive literature review using the PubMed database to analyze prevalence, anatomical carrier sites, current screening and decontamination protocols and guidelines, and methicillin-resistant S. aureus in cosmetic surgery was performed. The senior author's (L.R.) methicillin-resistant S. aureus infection experience and prevention protocols were also reviewed.
Results:
Nasal swabs detect only 50.5 percent of methicillin-resistant S. aureus colonization, and broad screening has noted the presence of methicillin-resistant S. aureus in the ear canal and umbilicus. Decolonization protocols within the orthopedic and cardiothoracic surgery literature have reduced rates of methicillin-resistant S. aureus surgical-site infections. There are no decolonization guidelines for plastic surgeons. Since instituting their decolonization protocol, the authors have had no cases of methicillin-resistant S. aureus infection in nearly 1000 cosmetic surgery procedures.
Conclusions:
There are very limited, if any, Level I or II data regarding methicillin-resistant S. aureus screening and decolonization. As the sequelae of a surgical-site infection can be disastrous, expert opinions recommend that plastic surgeons vigorously address methicillin-resistant S. aureus colonization and infection. The authors have developed and recommend a simple decolonization protocol that includes treatment of the umbilicus, ear canal, and nares to limit surgical-site infection and improve surgical outcomes.
Insights
Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) colonization is common. Addressing extra-nasal sites like the umbilicus and ear canal can reduce surgical site infections in cosmetic surgery.
Area of Science:
- Infectious Disease
- Plastic Surgery
- Microbiology
Background:
- Up to 20% of the population carries Staphylococcus aureus.
- 1-3% of the population is colonized with community-acquired methicillin-resistant S. aureus (CA-MRSA).
- Limited data exists on CA-MRSA carriage sites beyond the nose and their impact on cosmetic surgery site infections.
Purpose of the Study:
- To review the prevalence and anatomical carriage sites of CA-MRSA.
- To analyze current screening and decontamination protocols for CA-MRSA.
- To evaluate the effectiveness of decolonization in preventing surgical site infections in cosmetic surgery.
Main Methods:
- Comprehensive literature review of PubMed database.
- Analysis of prevalence, anatomical carrier sites, and existing CA-MRSA screening/decontamination protocols.
- Review of senior author's experience and prevention protocols for CA-MRSA infections.
Main Results:
- Nasal swabs detect only 50.5% of CA-MRSA colonization.
- CA-MRSA has been identified in the ear canal and umbilicus.
- Decolonization protocols in other surgical fields have reduced CA-MRSA surgical-site infections; authors experienced no CA-MRSA infections in nearly 1000 procedures after implementing a protocol.
Conclusions:
- Limited high-level data exists for CA-MRSA screening and decolonization in plastic surgery.
- Expert opinion recommends aggressive management of CA-MRSA colonization due to potential for disastrous surgical site infections.
- A simple decolonization protocol targeting the umbilicus, ear canal, and nares is recommended to improve outcomes.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
