脑脊液鼻漏的正确定位很困难,反复的施行手术就是正确定位失败的证明.X线所见蝶窦内气液面,曾被认为是窦漏介于蛛网膜下腔和蝶窦之间的征象.作者基于鼻腔的解剖学基础和13例病例分析,认为利用X线检查手段对脑脊液漏的正确定位困难,蝶窦气液面征也无特殊意义.作者分析的13列,6例为自发性脑脊液漏,7例是由手术或外伤所致.各例均经手术证实窦漏部位和校正.手术发现3例脑脊液漏发生在筛板,2例在额窦,5例在筛窦,3例在蝶窦.8例患者经一次手术治愈,3例需再次手术,2例进行了3次手术.13例患者都拍摄过立位副鼻窦片和头颅仰卧水平侧位片.大多数患者也进行过前后位,侧位和颅底位相的体层摄影检查.X线检查只发现3例患者的筛板,筛窦或蝶窦分别有骨质不联续,另10例无骨折征象.7例显示蝶窦气液面.9例筛窦粘膜密
Right cerebrospinal fluid rhinorrhea is difficult to locate the correct positioning, repeated operation is the correct proof of positioning failure .X line seen within the sphenoid gas level, has been considered sinus leakage between the subarachnoid and sphenoid sinus signs Based on the anatomical basis of the nasal cavity and the analysis of 13 cases, the author believes that it is difficult to correct the location of cerebrospinal fluid leakage by means of X-ray examination and there is no special significance for the gas-liquid surface of the sphenoid sinus. Cerebrospinal fluid leakage, 7 cases were caused by surgery or trauma .All cases were confirmed by sinus surgery site leakage and correction .Surgery found 3 cases of cerebrospinal fluid leakage occurred in the sieve plate, 2 cases in the frontal sinus, 5 cases in the ethmoid sinus, 3 cases In the sphenoid sinus, 8 patients were cured by a single operation, 3 required reoperation, and 2 performed 3 surgeries, and all 13 patients had either lateral varicose sinuses and skull supine lateral pelvis. Most patients also underwent surgery Before and after the position, lateral and skull phase phase tomography examination.X ray examination found only 3 patients with plate, ethmoid sinus or sphenoid bone were not continuous, and the other 10 cases without fracture signs.7 cases Show sphenoid air-liquid surface .9 cases of ethmoid sinus dense
