Abstract
OBJECTIVES: To determine the prevalence of maxillofacial fractures associated with persistent CSF leak, and to assess its bearing on clinical outcomes of consecutive patients managed at our centre. METHODS: This was a retrospective cross-sectional study. The medical records of patients over 11-year period were analysed for age, gender, etiology of injuries, duration between injury and presentation to the hospital, types of facial fracture and their treatments, treatment done to control CSF leak, and complication(s). Descriptive and bivariate statistics were computed. RESULTS: Overall, 1473 patients were evaluated, 66 (4.5%) presented with craniofacial injuries associated with persistent CSF leak after 5 days of non-surgical treatment. Males (92.5%, P= 0.0000) and those in the 21 to 30 years age group (59.1 %, P=0.01) were predominant. The most common (68.2%) type of fracture combination was Le Fort I, II and III, NOE, zygomatic complex and mandible. The commonest clinical presentation of CSF leak was rhinorrhea only, in 66.7% of patients (P= 0.001). CONCLUSIONS: This study shows that the prevalence of maxillofacial fractures associated with persistent CSF leak was low, which was 4.5% of patients that presented with persistent CSF leak and 84.9% of the cases resolved after treatment of the various maxillofacial fractures.
