“…Our results were not sinus‐specific, which may have limited this comparison. Furthermore, no significant difference was found between polyp and nonpolyp patients for all of the bacterial outcomes, which was comparable with other studies . In particular though, S. aureus was not seen more frequently in polyp patients, which contrasted with the finding of Van Zele et al…”

“…The pattern of bacterial isolates in our patients with CRS, either with or without polyposis, is similar to previous publications [7,10,11,12,13,14,15,16,17,21,22,23,24]. There was a high rate of aerobic pathogens, especially S. aureus and enteric bacteria, such as P. aeruginosa , and anaerobic species of Streptococcus and Proprionibacterium.…”

There are only limited data in the literature, and none specifically from the Middle East, on the pathogenic bacteria in chronic rhinosinusitis (CRS) as opposed to healthy nasal cavities and their association with disease severity. The present study was conducted in the department of head and neck surgery of a tertiary medical center. Middle meatal swabs were taken preoperatively from patients with CRS with nasal polyposis (CRSwNP) (n = 60), CRS without nasal polyposis (CRSsNP) (n = 50), and control patients with septal deviation (n = 26) or no nasal abnormalities (n = 27). Culture findings were compared among the groups and correlated with CRS severity. Positive pathogenic culture rates were 78% in the CRSwNP group and 64% in the CRSsNP group. Twenty pathogenic bacterial species were identified; the most common was Staphylococcus aureus (27%). The most common Gram-negative isolate was Citrobacter spp. (17%). Gram-negative species were significantly more prevalent in the CRSwNP group than the others. Mean Lund-Mackay scores were 12.8 in the CRSwNP group and 6.9 in the CRSsNP group, and were unrelated to the culture findings. Positive culture rates were significantly higher in the septal deviation (54%) than the nasal healthy group (26%), although both values were significantly lower than in the CRS groups. In conclusion, patients with CRS have higher rates of bacterial isolates than patients without CRS. CRSwNP is associated with more Gram-negative bacteria than CRSsNP, regardless of disease severity. The relatively high positive culture rate in patients with septal deviation merits investigation.

“…All those studies proved that sinus cavities are not sterile environment and that the culture rates and the bacterial spectrum are similar in various studies. Th e culture rate mostly depends upon the culture technique so that the bacterial growth was detected in up to 96% specimens [6]. In this study, the majority of bacteria detected in sinus mucosa were G+ bacteria, among which Staphylococci (epidermidis and aureus) and Streptococci (pneumoniae, viridans and spp.)…”

The aim of this study was the determination of bacteria present in maxillary and ethmoid cavities in patients with chronic sinusitis and to correlate these findings with bacteria simultaneously present in their nasopharynx. The purpose of this correlation was to establish the role of bacteria found in chronically inflamed sinuses and to evaluate if the bacteria present colonized or infected sinus mucosa. Nasopharyngeal and sinus swabs of 65 patients that underwent functional endoscopic sinus surgery were cultivated and at the same time the presence of leukocytes were determined in each swab. The most frequently found bacteria in nasopharynx were Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus spp., Streptococcus viridans and Streptococcus pneumoniae. Maxillary or ethmoidal sinus swabs yielded bacterial growth in 47 (72.31%) patients. The most frequently found bacteria in sinuses were Staphylococcus epidermidis, Staphylococcus aureus, Klebsiella spp. and Streptococci (pneumoniae, viridans and spp.). The insignificant number of leukocytes was present in each sinus and nasopharyngeal swab. Every published microbiology study of chronic sinusitis proved that sinus mucosa were colonized with bacteria and not infected, yet antibiotic therapy was discussed making no difference between infection and colonization. Chronic sinusitis should be considered a chronic inflammatory condition rather than bacterial infection, so routine antibiotic therapy should be avoided. Empiric antibiotic therapy should be prescribed only in cases when the acute exacerbation of chronic sinusitis occurs and the antibiotics prescribed should aim the usual bacteria causing acute sinusitis. In case of therapy failure, antibiotics should be changed having in mind that under certain circumstances any bacteria colonizing sinus mucosa can cause acute exacerbation of chronic sinusitis.
