[The use of ultra-sound in sinus disease (author's transl)].

The inclusion of ultra-sound in the routine diagnosis of sinus disease reduces the margin of error by about 6%, compared to that using clinical records and x-ray. The investigator should have sufficient experience in operating the ultrasonic equipment. Especially valuable is the ultrasonic diagnosis in cases of discharge, mucosal swelling or tumor in the sinus, as well as in cases of sinus examination of children and for control of patients having had conservative treatment or operations.
