Bacterial culture of material from blind swabs of the nasal cavity or from purulent nasal secretions is not recommended, as results are not reliable. Therefore, patients who require antibiotic therapy will generally be treated empirically in the primary care setting, with antibiotic choice based on likely pathogen and susceptibility. (See "Treatment" below).
Endoscopic cultures can be performed with minimal morbidity in the otolaryngologist's office (show figure 2) and are better tolerated than classic antral puncture with a large bore trocar or needle passed through the canine fossa or inferior meatus [27-29] . Endoscopically-guided middle meatal cultures correlated with cultures performed during maxillary antrostomy in 86 percent of patients in one study [30] and with maxillary punctures in 90 percent in a small prospective series [31] .
Endoscopic or sinus aspirate culture, while not indicated in routine medical practice, should be considered if there is a suspicion of intracranial extension of the infection or other serious complications. Culture may also be helpful in patients where atypical pathogens may be suspected, including patients with nosocomial sinusitis, immunocompromise, cystic fibrosis, or recent hospitalization. Cultures are also indicated in patients with documented sinusitis who are not responding to empiric antibiotic therapy.
