诊断脑脊液漏,可依据耳或鼻滴出水样液的病史,X线所见和漏液中糖、蛋白质、电解质含量的分析,但有许多病例,漏液为血和鼻腔分泌物严重污染,可使通常用以鉴定脑脊液的各种化学试验结果不正确。另外,泪液亦可被误为脑脊液,因为两者的葡萄糖含量几乎相等。当从鼻或耳得到的标本太少,以至不得不采用吸取法时,也可能发生污染。在这些情况下,常规化学试验所得资料往往是不可靠的。包括使用造影剂的X线检查、鞘内注射染料与放射性同位素脑池造影术,是脑脊液漏定位的最常用方法,这些检查虽有帮助,但并不一定能显示漏液的部位,而鞘内注射且有技术上的限 Diagnosis of cerebrospinal fluid leakage can be based on the history of ear drops or nasal drops of water samples, X-ray findings and leakage of sugar, protein, electrolyte content analysis, but there are many cases of leakage of blood and nasal discharges serious pollution, The results of various chemical tests commonly used to identify cerebrospinal fluid can be incorrect. In addition, tears can also be mistaken for cerebrospinal fluid, because both glucose content is almost equal. Contamination can also occur when too few specimens are obtained from the nose or ears, and even if suction methods are obliged. Under these circumstances, the information obtained from routine chemical tests is often unreliable. Including the use of contrast agent X-ray examination, intrathecal injection of dye and radioactive isotope brain pool imaging is the most common method of cerebrospinal fluid leakage positioning, although these tests may help, but does not necessarily show the site of leakage, and intrathecal Injected and technically limited
