Cerebrospinal fluid leak prevention after translabyrinthine removal of vestibular schwannoma.
OBJECTIVE
The purpose of the report was to present an update on the authors' results for prevention and management of cerebrospinal fluid (CSF) leak after translabyrinthine approach for vestibular schwannoma.


METHODS
: Retrospective case review.


METHODS
The study was conducted at Gruppo Otologico (Piacenza, Italy), a tertiary referral center for neurotology and skull base surgery. In all, 710 patients underwent translabyrinthine approach for the removal of vestibular schwannoma at that institution between April 1987 and December 2002. The medical records were retrospectively reviewed to identify tumor size, the incidence of postoperative CSF leak, and its treatment.


RESULTS
The overall rate of CSF leak was 1.4%.


CONCLUSIONS
The use of proper surgical technique minimizes the risk of CSF leak. Study results show that the continued application of the authors' proposed preventive measures resulted in the maintenance of a low rate of CSF leak. Immediate management of CSF fistulae helps prevent meningitis.
