ABSTRACT

Introduction: Chronic rhinosinusitis is defined as inflammation of the nasal mucosa and paranasal sinuses with a duration greater than 12 weeks. The RSC is subclassified as with polyps and without polyps. Currently, one of the most important theories for the development of polyps is the presence of Staphylococcus aureus and its superantigen theory in which the production of enterotoxins and the formation of biofilm are involved. Objective: Determine the prevalence and relationship of Staphylococcus aureus in patients with chronical rhinosinusitis with polyps, in the population of the «Ignacio Zaragoza» Regional Hospital, ISSSTE. Material and methods: Descriptive, analytical and prospective study. Patients over 18 years of age assigned to the Otolaryngology Service with a diagnosis of chronic rhinosinusitis were included, taking biopsies of the polypoid tissue with sterile material by Sterrad® to perform the culture and determine the presence of Staphylococcus aureus. To define the relationship of Staphylococcus aureus and chronic rhinosinusitis with polyps, the Pearson correlation was used through the SPSS. Results: We had a total population of 20 patients, 12 women and 8 men, of which six patients (30%) had presence of Staphylococcus aureus, six patients (30%) with Staphylococcus epidermidis, and eight patients (40 %) with other microorganisms. Demonstrating a Pearson correlation between microorganism and multiple endoscopic surgeries by polyposis of 0.780. Conclusions: This study shows that patients with chronic rhinosinusitis with polyps and Staphylococcus aureus have a torpid evolution despite the diversity of surgical medical treatment granted.
