Acute sinusitis in children--symptoms, clinical findings and bacteriology related to initial radiologic appearance.

In a series of 175 children with suspected sinusitis the symptoms and clinical signs were compared with the radiologic and bacteriologic findings. URI, purulent nasal secretion and pain were the main symptoms predicting radiologic changes. In 75% of the patients the presence of two or three of these symptoms was co-existent with major radiological changes. As assessed by nasopharyngeal culture Haemophilus influenzae seemed to be the major pathogen.
