[Use of unidimensional echography in the diagnosis of maxillary sinusitis in children].

Unidimensional echography using a Sinuskan-101 unit was applied to examine 167 children. The results showed that ultrasonic examination of maxillary sinuses may yield important information about their condition. Echographic parameters depended on the type of maxillary sinusitis. In patients with exudative forms the dark zone constituted 4-7 light diodes, in patients with productive forms it comprised 2-5 light diodes, in 5 patients with cystic form it depended on the cyst size and amounted to 5-10 light diodes. Echograms taken at various time intervals helped to follow the course of disease and efficacy of therapy. In 3 patients, for whom X-raying was counterindicated, suppurative maxillary sinusitis was diagnosed echographically and confirmed by punctures of maxillary sinuses.
