OBJECTIVE: To compare primary spontaneous cerebrospinal fluid @entity292 (PSF) and late traumatic @entity292 (LTF). STUDY DESIGN: Historical cohort study. SETTING: Academic medical center. SUBJECTS AND METHODS: There were 26 @entity1 with PSF in group 1 and 23 @entity1 with LTF in group 2. Gender, age, location of the osteomeningeal breach, time between symptom onset and surgical treatment, number of episodes of @entity693 , and density of the incidence of @entity693 were compared. Two factors related to chance of curing the @entity292 were analyzed: etiological type and @entity292 location. RESULTS: In group 1, 92% of @entity1 were @entity1 (mean age 50 years). In group 2, 74% were @entity1 (mean age 22 years). PSF predominated in the sphenoid sinus (60%), whereas LTF occurred mainly in the ethmoidal (33%) and frontal (28%) sinuses. Time between presentation and surgical treatment was 28.9    50.2 and 12.4    15.5 months in groups 1 and 2, respectively (P = .166). There were 0.6 and 1.3 episodes of @entity693 per @entity1 in groups 1 and 2, respectively (P = .038). Density of the incidence of @entity693 was 0.1 and 0.2 events per @entity1 -month, respectively (P = .016). The 4 not-cured @entity1 had @entity75 and were from the PSF group. CONCLUSIONS: Female sex, middle age, and @entity292 were prevalent in @entity1 with PSF. @entity1 with LTF were twice as likely to develop @entity693 , and male sex, young age, and leaks through the frontal and ethmoidal region were more common in this case. Osteomeningeal breach located in the sphenoid sinus had a lower chance of sealing.
