A complete resection of the mass while preserving the facial n...

OBJECTIVE To evaluate long term facial nerve function in patients undergoing VS resection and to correlate tumor size and facial function in a long-term follow-up. METHOD Transversal study of 20 patients with VS operated by the retrosigmoid approach. House-Brackmann Scale was used pr...
