Cranionasal fistula in pediatric population: Is endonasal endoscopic approach effective?

Purpose: To study the efficacy and safety of endoscopic endonasal repair of CSF leak in pediatric population. Study design: A prospective study in a tertiary care center. Patients and methods: All the cases with a age of less than 14 years with a diagnosis of CSF rhinorrhoea were included in the study. These were subjected to detailed examination, radiological evaluation using computed tomographic cisternography and MRI if required. These cases were then subjected to endoscopic endonasal repair of the fistula using the technique described in the text. Results: There were 25 cases in the study with a mate predominance and trauma responsible for 22 of these and spontaneous teak in 3 of the cases. The majority of these leaks were from cribriform plate area. After the repair, there was no teak in 24 of these cases and 1 case with recurrence did well after second surgery. Discussion: The prior work on the entity of CSF rhinorrhoea in children consists of a few case reports only and ours is the largest series on encloscopic repair of the CSF leak in children showing it to be safe and effective with a success rate of 96%. Conclusion: Endoscopic closure of the cranio nasal fistula is associated with a high degree of success (96% in our series) and has significantly less morbidity and mortality when compared with the craniotomy approach. Hence it can be concluded that it is the standard of care for the pediatric population as well. (c) 2007 Elsevier Ireland Ltd. All rights reserved.
