An alternative method for dealing with cerebrospinal fluid fistulae in inner ear deformities.

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.
