MVD

MVD was performed with the transposition method through the standard retrosigmoid approach. The patient was placed in the lateral park bench position and retrosigmoid craniotomy was completed prior to the microscopic procedure. Decompression was performed through the infrafloccular approach for HFS and GPN, and the supracerebellar approach for TN. Brainstem auditory evoked potentials were monitored routinely during MVD for HFS.³⁾ All microsurgical procedures in this series were performed by the same surgeon (K.A.)
