Culture

In general, cultures of the nasal cavity have not been readily used in the pediatric population. The primary reasons are poor patient compliance and the inability to obtain an uncontami-nated specimen. Recently cultures of the middle meatus have shown a high correlation with antral punctures.9 In the cooperative patient, endoscopically directed cultures of the middle meatus may be very useful, particularly in communities with increased resistance. Cultures of the maxillary sinus in patients who have complicated acute sinusitis or in those who fail to respond appropriately are indications that a culture should be obtained by antral puncture.1
