Abstract
The purpose of this study was to investigate and summarize the characteristics of spontaneous cerebrospinal fluid rhinorrhea cases and the efficacy of transnasal endoscopic repair of spontaneous cerebrospinal fluid rhinorrhea with the assistance of computer-assisted navigation system. This is a retrospective study including 21 adult patients with spontaneous cerebrospinal fluid rhinorrhea who underwent transnasal endoscopic repair with the assistance of computer-assisted navigation system between January 2007 and December 2017. Data collected included patient demographics, body mass index, patient symptoms, biochemical findings, radiographic findings, location of defect, type and size of defect, type of repair, follow-up time, reoccurrence, and complications. Spontaneous cerebrospinal fluid rhinorrhea was more commonly seen in females who were middle-aged and overweight in our series. The effluent was determined as cerebrospinal fluid by testing of glucose concentration and β2-transferrin. The location of the lesion was determined by rigid nasal endoscopy combined with radiologic study. Intraoperatively, the skull base defects were found most frequently on the ethmoid roof in 12 cases (57.1%), followed by the cribriform plate i...Continue Reading
