OBJECTIVE: To detail our experience in the management of cerebrospinal fluid (CSF) leak following posterior cranial fossa surgery by the retrosigmoid approach.
PATIENTS AND METHODS: 412 patients who underwent posterior cranial fossa surgery by the retrosigmoid approach for a variety of diseases were included in the study.
RESULTS: There were 32 CSF leaks (7.7%) in the 412 patients. Of these, 16 were leaks from the incision site (50%) and 16 (50%) were CSF rhinorrheas. The CSF leaks were documented in 22 of the vestibular schwannoma surgeries (68.7%) and 10 of the vestibular nerve sectioning surgeries (31.3%). No CSF leak was seen following microvascular decompression and auditory brain stem implantation surgeries. Ten patients could be treated conservatively. Twelve patients needed the placement of a lumbar drainage. Surgical reexploration was performed in 10 patients.
CONCLUSIONS: Initially, a conservative treatment should be instituted in the case of a CSF leak. If the conservative treatment fails, the placement of a lumbar drainage should be considered. Patients that do not respond to lumbar drainage require surgical reexploration. The abovementioned algorithm represents the safest and best option in the presence of a CSF leak, as confirmed by the absence of recurrences or multiple revisions in this study.
