| chronic sinusitis in children. | in children, sinusitis is a common, generally uncomplicated, and self limiting disease which drops with age. the diagnosis is difficult because of relatively non specific signs and symptoms that overlap with viral upper respiratory infection and allergy. plain paranasal sinus radiographs are not adequate, in determining the extent of involvement in recurrent or chronic sinusitis and so ct scan has become the standard. viral illness appears to be the most common predisposing factor. immune defect ... | 1997 | 9444376 |
