  • Title: Staphylococcus aureus and endoscopic sinus surgery.
    Author: Lin A, Busaba NY.
    Journal: Curr Opin Otolaryngol Head Neck Surg; 2006 Feb; 14(1):19-22. PubMed ID: 16467633.
    Abstract:
    PURPOSE OF REVIEW: The current recommendation for the choice of empiric antibiotic therapy of chronic rhinosinusitis is based on the bacteriology of acute rhinosinusitis. Staphylococcus aureus has been found consistently in cultures from patients with chronic rhinosinusitis. New studies have examined the role of Staphylococcus aureus in the pathogenesis and clinical course of chronic rhinosinusitis, both before and after surgical therapy. The consequence of antibiotic resistance, on the course of chronic rhinosinusitis and its treatment, has also been examined. RECENT FINDINGS: Several recent studies have confirmed past literature demonstrating a high incidence of sinus cultures positive for Staphylococcus aureus growth in patients with chronic rhinosinusitis. Moreover, one study reported that Staphylococcus aureus is common in patients with persistent chronic rhinosinusitis after endoscopic sinus surgery. These studies, however, have not shown that this bacterium is a significant factor in the development of chronic rhinosinusitis or a predictor of the severity of symptoms. Other studies did not support the notion of increased antibiotic resistance in chronic rhinosinusitis, although there is some evidence that antibiotic resistance may lead to refractory cases of the disease. The standard treatment, of multiple courses of empiric antibiotics followed by surgery, was not shown to increase the prevalence of methicillin-resistant Staphylococcus aureus. SUMMARY: A review of recent literature shows a high incidence of positive cultures for Staphylococcus aureus from the sinuses of patients with chronic rhinosinusitis, both before and after surgery, but has not produced convincing evidence that Staphylococcus aureus has a significant role in the pathogenesis or clinical course of the disease.
