[Evaluation of sonography in diseases of the paranasal sinuses].

The diagnosis of disorders of the paranasal sinuses by ultrasound has grown in importance during the last few years and has become easier due to developments in ultrasonic equipment. Nevertheless it seemed to be necessary to evaluate the advertising claims that the method is as reliable as radiography in the diagnosis of pathological conditions of the paranasal sinuses. We investigated 188 maxillary sinuses of adults by sinuscopy and compared the findings to those of radiography and ultrasound. The results are given and discussed.
