Abstract

OBJECTIVE: To review the management of cerebrospinal fluid leak after vestibular schwannoma removal reported in the literature and to present a novel approach to management of recalcitrant cases.

DATA SOURCES: MEDLINE and PubMed literature search using the terms "cerebrospinal fluid leak" or "cerebrospinal fluid fistula" and "acoustic neuroma" or "vestibular schwannoma" covering the period from 1985 to present in English. A review of bibliographies of these studies was also performed.

STUDY SELECTION: Criteria for inclusion in this meta-analysis consisted of the availability of extractable data from studies presenting a defined group of patients who had undergone primary vestibular schwannoma removal and for whom the presence and absence of cerebrospinal fluid leakage was reported. Studies reporting combined approaches were excluded. No duplications of patient populations were included. Twenty-five studies met the inclusion criteria.

DATA EXTRACTION: Quality of the studies was determined by the design of each study and the ability to combine the data with the results of other studies. All of the studies were biased by their retrospective, nonrandomized nature.

DATA SYNTHESIS: Significance (p < 0.05) was determined using the chi test.

CONCLUSIONS: Incisional cerebrospinal fluid leakage responded well to local management and lumbar drainage. Rhinorrhea often necessitated surgical intervention. No specific reoperation techniques correlated exclusively with better reoperation outcomes. The transaural/transnasal approach presents an alternative for surgical management of cerebrospinal fluid rhinorrhea.
