BACKGROUND: A number of @entity1 with @entity174 have cerebrospinal fluid (CSF) leak that may result in @entity149 . Commonly, CSF leak occurs following @entity130 , but the etiology and pattern of this disorder are different from region to region. This study aims to evaluate the distribution of CSF leak in @entity1 with maxillofacial @entity174 in Isfahan province, Iran. @entity1 AND METHODS: In this retrospective cross-sectional study, 1,287 medical files of @entity1 admitted to a medical center with head and @entity130 were evaluated during a 7-year period (2004-2010). Data was obtained using descriptive analysis. RESULTS: Of the 1,278 @entity1 with head and maxillofacial @entity174 , 16 (1.25  %) males and one (0.07  %) female had CSF leak; all these cases had @entity174 . Of these, 52.9  % had maxillary @entity174 , 23.5  % nasal @entity174 , 41.1  % orbital @entity174 , 11.7  % mandibular @entity174 , 23.5  % frontal @entity174 , and 41.1  % had more than one site of @entity174 . 58.8  % had @entity5254 and 41.2  % @entity2972 . Of all these @entity1 with CSF leak, 8 (47  %), 2 (11.8  %), and 7 (41.2  %) cases were treated spontaneously, using lumbar drain placement, and by surgical intervention, respectively. CONCLUSIONS: @entity5173 was observed most frequently in @entity1 with @entity174 in the zygomatic and maxillary bone, and mostly exhibited itself as @entity5254 and/or @entity2972 . All cases with CSF leak had @entity174 as well. However, post-traumatic CSF leaks are uncommon and are generally treated without surgical intervention (59  %). Distribution of CSF leak varies from one region to another and knowing this fact helps to manage the injury and prevent the complications.
