既往诊断脑脊液鼻漏的各种方法,其可靠性和安全性均存在问题。作者报告采用放射性同位素(RI)计数法来确定有无脑脊液鼻漏,并可同时做出定位诊断,可靠性甚高。方法:用3号丝线结扎1cm见方、2mm厚的棉球备用。腰椎穿刺向脊髓腔内注入~(111)In-DTPA1mCi。1小时后将带线棉球置于双侧蝶筛隐窝、嗅裂、中鼻道6处,同时在侧齿龈和颊粘膜间放置带线棉球,这些部位预先用2%利多卡
Previous methods of diagnosing cerebrospinal fluid rhinorrhea have problems of reliability and safety. The authors report using radioisotope (RI) counting to determine whether there is cerebrospinal fluid rhinorrhea, and can make positioning diagnosis at the same time, with high reliability. Method: No. 3 silk ligature 1cm square, 2mm thick cotton ball spare. Lumbar puncture injects ~ (111) In-DTPA1mCi into the spinal cavity. One hour later, the cotton thread with the thread was placed in the bilateral butterfly sieve crypts, olfactory fissure and middle meatus 6, while the cotton thread with thread was placed between the lateral gingival and buccal mucosa. These areas were pre-treated with 2%
