Comparison of ultrasound and X-ray maxillary sinus findings in school-aged children

A total of 663 unselected 7-, 10- and 14-year-old school children were examined for both ultrasound and X-ray maxillary sinus findings. Ultrasound and X-ray findings were normal in 84.5% and 83.9% of the children, respectively. In a comparison of the findings, the sensitivity of ultrasound examination compared to abnormal maxillary sinus X-ray findings was low. However, a negative ultrasound finding was a sound basis for excluding the disease. According to the results of the present study, it is perhaps justified to say that a negative ultrasound finding excludes the occurrence of radiographic sinusitis, whereas a positive ultrasound finding has little or minor significance.
