PURPOSE
The clear sinus sign has been described in facial computed tomography (CT) as an indication of the absence of fluid in the paranasal sinuses. It is a highly reliable criterion to exclude fracture involving the paranasal sinus wall. Very scarce data on this sign on head CT scan is currently available. We conducted the present study to assess the usefulness of the clear sinus sign on head CT scan to exclude paranasal sinus fracture.
MATERIALS AND METHODS
A retrospective cross-sectional review of the medical records and head and facial CT images was performed for 80 trauma patients with a total of 640 paranasal sinuses. The presence and absence of paranasal sinus fracture was recorded and analyzed.
RESULTS
The clear sinus sign was found in 207 paranasal sinuses (32.3%) on head CT, and none of these had a paranasal sinus fracture (P < .001).
CONCLUSIONS
The presence of the clear sinus sign on head CT scans is an excellent indication for exclusion of a paranasal sinus fracture in trauma patients.
目的
在面部计算机断层扫描（CT）中，清晰鼻窦征被描述为鼻窦内无液体的表现。它是排除累及鼻窦壁骨折的高度可靠标准。目前关于头部CT扫描中此征象的数据非常稀少。我们开展本研究以评估头部CT扫描中清晰鼻窦征在排除鼻窦骨折方面的实用性。
材料与方法
对80例创伤患者的病历以及头部和面部CT图像进行回顾性横断面研究，共计640个鼻窦。记录并分析鼻窦骨折的有无情况。
结果
在头部CT上，207个鼻窦（32.3%）出现清晰鼻窦征，其中无一例发生鼻窦骨折（P <.001）。
结论
头部CT扫描出现清晰鼻窦征是创伤患者排除鼻窦骨折的极佳指征。
