A flexible fiberscope (Olympus PNF-type 2), with a diameter of 3.4 mm, was used to examine velopharyngeal function. In our study, a large number of subjects were young and even in these subjects it was easy to examine the velopharynx. However, examination of intranasal structures such as the maxillary ostium and the ethmoidal system was difficult in younger subjects. Therefore, the diagnosis of sinusitis was based on the findings obtained by anterior rhinoscopy and roentgenography.
Computed tomography is commonly used for examination of paranasal sinus diseases in our institution. However, computed tomography is not recommended for all younger subjects because exposure to radioactive rays should be minimized at this age. Furthermore, plain roentgenograms are as useful as computed tomography in the diagnosis of nasal sinusitis.
In the present study, the
