In 71 patients with rhinosurgical closed fronto-basal cerebrospinal fluid fistula the pre- and intra-operative findings are compared. Cerebrospinal fluid rhinorrhea in 80% and purulent meningitis in 44% were seen. In X-ray 52% fractures and 32% cloudiness of the paranasal sinuses were found, there were 21% false negative results. By nuclear medical examination the cerebrospinal fluid leak was identified in 59%, the result was false negative in 15%. The site of the cerebrospinal fluid fistulas could be preoperative determinated by clinical signs in 96%, by X-ray in 22%, and by scintigraphy in 44%.
