The eight patients thought to have radiological evidence of acute sinusitis all had air-fluid levels in the maxillary sinuses. In one patient, the findings were bilateral; in seven, unilateral.We certainly agree that the literature cited by Dr Ravenel indicates that unsuspected abnormal radiological findings of the sinuses are encountered in asymptomatic young children. However, these studies have limited relevance to our article. Our study was intended to show a costbenefit effectiveness of a number of laboratory tests employed in the evaluation of
