自发性脑脊液(cerebrospinal fluid,CSF)鼻漏起病隐匿,除鼻漏外可无其他症状,但上呼吸道感染后则可能继发颅内感染,严重时可危及生命;又因缺乏原发病因所提示的线索,往往难以准确定位,从而影响有效治疗。因此,对其漏口进行准确定位,是临床上成功处理自发性CSF鼻漏的关键。本文 Nasal leakage of cerebrospinal fluid (CSF) is insidious, except for the presence of rhinorrhea. However, there may be secondary to intracranial infection after upper respiratory tract infection and may be life-threatening if it is serious. In the absence of primary etiology Tips clues, often difficult to accurately locate, thus affecting the effective treatment. Therefore, accurate positioning of its leakage port is clinically the key to successful treatment of spontaneous CSF rhinorrhea. This article
