Objective:
This study aimed to review the management of cerebrospinal fluid (CSF) fistulae in the setting of developmental inner ear deformity.
Study Design:
The study design was a case review, close examination of preoperative radiology, and corresponding intraoperative images.
Technique:
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.
