title: [Improved method of ultrasonic diagnosis of maxillary sinus diseases in children].
abstract: A modified technique of ultrasonic diagnosis of accessory nasal sinus diseases based on an analysis of the profile of echograms has been developed. A correlation between the profile and pathological changes in the Highmore antrum has been found. It has been shown that the cystic fluid has a characteristic difference between the intensity of the start and echo impulses. Echograms of a cyst and its capsule reveal that they are significantly heterogeneous. Pus is characterized by a pronounced ultrasound absorption, fluid pus and thick pus showing different response. Plasma and blood are characterized by a significant ultrasound absorption and sufficient homogeneity. An interpretation of an echogram obtained under clinical conditions is presented.
