Waters' view in children with Sinusitis

Waters' occipito-mental view of 433 children with prolonged upper respiratory infection was reviewed. In about 30% of cases no abnormal findings were detected. 68% had bilateral sinusitis, most frequently total opacity or air-fluid level, especially in children before school age. Seven children (1.7%) had polypoid lesions. Reexamination was done in 15% of cases. In children below four years of age Waters' view is not always technically optimal. Hence X-ray findings should be assessed critically. After the children have reached school age, radiographic evaluation of sinuses becomes as reliable as with adults. (orig.)
