Microbiology of Chronic Maxillary Sinusitis in Adults: Isolated Aerobic and Anaerobic Bacteria and their Susceptibility to Twenty Antibiotics

Aspirates of 72 chronically inflamed maxillary sinuses were processed for aerobic and anaerobic bacteria. Bacterial growth was present in 66 of the 72 specimens (92%). Anaerobic bacteria were isolated in 58 of the 66 culture-positive specimens (88%). Anaerobes only were recovered in 37 cases (56%) and in 21 (32%) they were mixed with aerobic or facultative bacteria. Aerobic or facultative bacteria were present in eight cases (12%). A total of 185 isolates (2.8 per specimen) — 131 (2.0 per specimen) anaerobes and 54 (0.8 per specimen) aerobes or facultatives — were isolated. The predominant anaerobic organisms were anaerobic cocci and Bacteroides sp, and the predominant aerobes or facultatives were Streptococcus sp and Staphylococcus aureus. Twelve of the 27 Bacteroides sp that were tested for β-lactamase (44%) produced the enzyme. These findings indicate the major role of anaerobic organisms in chronic sinusitis.

Abstract Aspirates from 50 chronically inflamed maxillary sinuses were processed for aerobic and anaerobic bacteria. Bacterial growth was present in 48 (96%) specimens. There were 110 bacterial isolates (2.2/specimen). Forty of the isolates were aerobic or facultative organisms (0.8/ specimen). The predominant aerobic or facultative organisms were Staphylococcus aureus, coagulase-negative staphylococcus (CNS), S. pneumoniae, E. coli, H. influenzae and P. aeruginosa. Seventy anaerobes were isolated (1.4/specimen), Prevotella spp, Peptostreptococcus spp., Porphyromonas spp. and bacteroides spp. being predominant. These findings illustrate the presence of polymicrobial aerobic-anaerobic flora in patients with chronic maxillary sinusitis.

Chronic Maxillary Sinusitis

Background The histopathology and microbiology associated with silent sinus syndrome (SSS) have not been well described. Objective This study details the histopathological and microbiological characteristics in addition to radiographic findings of SSS in comparison to those of chronic maxillary sinusitis (CRS). Methods 42 patients diagnosed with SSS at Mayo Clinic Hospital in Arizona were identified. Paranasal computed tomography scans of the 42 SSS patients as well as 42 matched CRS patients were analyzed in order to assess differences in the prevalence of septal spurs/deviation. 20 of the SSS patients and 19 of the matched CRS patients also had histopathology and microbiology reports, which were compiled and summarized. Additionally, 19 SSS and 19 matched CRS patients were contacted via phone survey for a more complete patient history regarding maxillary dental disease/surgery. Results SSS patients have a significantly higher prevalence of septal spurs/deviation than CRS patients. The microbiomes of SSS patients more closely resemble those of healthy controls than those of CRS patients. Analysis of the histopathology of SSS reveals chronic, non-specific inflammation similar to that seen in non-eosinophilic CRS without polyps. SSS patients were significantly more likely to have a history of maxillary dental disease requiring surgery. Conclusion These data support the hypothesis that the pathogenesis of SSS is more likely due to anatomical/mechanical factors than inflammatory/microbiological factors.
