Answer

Cultures of nasal secretions are of limited value because they are usually contaminated by normal flora. Consequently, cultures are not routinely obtained in the evaluation of acute sinusitis; however, they should be obtained in a patient in intensive care or with immunocompromise, in children not responding to appropriate medical management, and in patients with complications of sinusitis.
