Endoscopic repair of cerebrospinal fluid leak in paediatric patients

BackgroundIn scientific literature exist fewer case series regarding endoscopic treatment of paediatric cerebrospinal fluid fistulas. Compared to craniotomy endoscopic repair does not reach wider consent even if craniotomy carries higher complications rate.ObjectiveThe aim of the present study was to report our institutional experience on paediatric cerebrospinal fluid leak to demonstrate the safety and efficacy of the endoscopic approach in a variety of cases.MethodsClinical records of all paediatric patients who underwent endoscopic repair of anterior and middle fossa skull base defects are reviewed for several parameters.Results10 patients were enrolled, 6 males and 4 females with a mean age of 10 years. The aetiology of the leak was congenital in 2 cases, trauma-induced in 6 cases and iatrogenic in 2 cases. In all the cases the defect was localized by computed tomography. Remedial was obtained using multiple grafts technique with autologous materials during a single procedure in all but one case, this one case requiring a second operation for delayed recurrence. The mean follow-up duration is 36 months.ConclusionCSF fistulas can be approached in paediatrics of any age with high success and low complications rate using the endonasal technique.
