A-scan and B-scan sonography was performed in 86 patients with fractures in the paranasal region (73 blow-out, 8 ethmoidal, 5 frontal sinus fractures). In all of them echography provided a correct diagnosis by delineating fracture lines and bone fragment dislocation. Additionally, sonography detected a haematosinus in 17, and a subperiosteal haematoma in 6 patients, respectively. Although echography can never replace radiologic diagnostics, it should be performed in the primary evaluation and in the follow-up of all patients with paranasal traumatology because of its high accuracy.
