Head/Face/Neck Paresthesias Rate (%) 17/84 (20%) 13/37 (35%) 23/43 (53%) 36/84 (45%) *
Incidence of CSF Leak (%) 0/84 (0%) ** 2/37 (5%) 0/43 (0%) * 2/80 (3%)

Incidence of Hearing Changes (%) 2/84 (2%) 6/37 (16%)* 6/43 (14%)* 12/80 (16%) *
  1. * P < 0.05 compared to BA
  2. ** P < 0.05 compared to MVD
  3. Combined = Microvascular Decompression with or without Rhizotomy
