Radiography of the paranasal sinuses--one or three views?
A prospective study of 100 adult patients undergoing paranasal sinus radiography was performed. Two experienced radiologists independently assessed a single occipitomental view and, at a later date, the traditional three projections, i.e. occipitomental, occipitofrontal and lateral. There was 99% intra-observer agreement between the diagnosis on a single projection compared with all three films. In five cases, the frontal sinuses were difficult to assess mainly due to poor radiography, and in defined circumstances additional views may be required occasionally. We conclude that with greater attention to radiographic technique the occipitomental view alone is sufficient for diagnostic purposes.
