In review of 1544 patients with both head computed tomography (CT) examinations and skull radiographs, 150 patients were found to have a history of acute head trauma. Twenty-nine of these patients had sphenoid sinus effusions. Ninety-three percent (27/29) of those cases had abnormal CT examinations, as compared with 48% (58/121) of cases without sphenoid effusions. Of the patients with sphenoid effusions, 31% (9/29) had intracerebral hematomas, 24% (7/29) had extracerebral hematomas, 13% (4/29) had pneumocephalus, and 13% (4/29) had cerebral edema. We conclude that the presence of posttraumatic sphenoid sinus effusion on the skull radiograph is a sensitive sign for intracranial damage and serves as an emergent indication for head CT.
在对1544例同时进行头部计算机断层扫描（CT）检查和颅骨X线片检查的患者进行回顾时，发现150例患者有急性头部外伤史。其中29例患者出现蝶窦积液。这些病例中有93%（27/29）的CT检查异常，而无蝶窦积液的病例中这一比例为48%（58/121）。在有蝶窦积液的患者中，31%（9/29）有脑内血肿，24%（7/29）有脑外血肿，13%（4/29）有气颅，13%（4/29）有脑水肿。我们得出结论，颅骨X线片上出现创伤后蝶窦积液是颅内损伤的一个敏感征象，可作为头部CT检查的紧急指征。
