title: An alternative method for dealing with cerebrospinal fluid fistulae in inner ear deformities.
abstract: OBJECTIVE
  This study aimed to review the management of cerebrospinal fluid (CSF) fistulae in the setting of developmental inner ear deformity.
  
  
  METHODS
  The study design was a case review, close examination of preoperative radiology, and corresponding intraoperative images.
  
  
  METHODS
  A definitive method of CSF fistula closure is described using previously known techniques used commonly in skull base surgery.
  
  
  CONCLUSIONS
  The use of a multiple-level, reinforced wound closure technique is necessary to definitively close CSF fistulae in extreme inner ear deformity and to prevent further episodes of CSF leak and meningitis.
