[Digital diaphanographic diagnostics of frontitis].

A diaphanographic technique for the examination of frontal sinuses modified based on computed technologies is proposed. Digital diaphanograms were fed into the operational system of a personal computer and treated the images using the specially developed programs. The quantitative analysis of digital diaphanographic data was performed with the help of local densitometry of diaphanograms. It was shown that optical density of diaphanograms reflects the degree of inflammatory changes in the sinus. The method applied in this study allowed to improve the accuracy and reliability of diagnosis of frontitis and to monitor efficiency of its treatment.
