Comparative echography and x-ray findings in suspected paranasal sinus disease reveal a good liability of negative x-ray reports. Positiv findings i.e. the diagnosis of mucous membrane thickening in the maxillary sinus and clouding of the frontal sinus are often misleading. Echography is reliable in diagnosing retention of sinus secretions. The patency of the maxillary ostium for air was tested in patients with complete opacity of the sinus. There was a significant difference between air or fluid containing sinuses, using echography as a control. Complete radiographic opacity has no bearing on ostial patency. In air containing sinuses with radiographic opacity, ostial permeability is slightly affected, the ostium nevertheless being patent for respiratory pressure changes.
疑似鼻窦疾病的超声检查与X线检查结果对比显示，X线报告阴性的可靠性较高。阳性结果，即上颌窦黏膜增厚及额窦混浊的诊断，往往具有误导性。超声检查在诊断鼻窦分泌物潴留方面可靠。对鼻窦完全不透明的患者测试了上颌窦口的通气情况。以超声检查为对照，含气或含液鼻窦之间存在显著差异。完全的放射学不透明与窦口通畅情况无关。在放射学不透明的含气鼻窦中，窦口通透性略有影响，但窦口在呼吸压力变化时仍保持通畅。
