title: Corticotomy closure avoids subdural collections after hemispherotomy.
abstract: BACKGROUND
  Subdural collection is a possible adverse event that can occur after hemispherotomy.
  
  
  OBJECTIVE
  : We describe our surgical technique to avoid subdural collection after peri-insular hemispherotomy in children.
  
  
  METHODS
  Since 2008, we have closed the corticotomy with interrupted pial sutures and fibrinogen glue in 16 patients.
  
  
  RESULTS
  This operative technique stopped the occurrence of postoperative subdural collection and was not associated with an increased incidence of postoperative hydrocephalus.
  
  
  CONCLUSIONS
  We recommend closing ventricular access after functional hemispherotomy, notably in patients who have had a stroke.
