Inferior Ventrolateral Approach for Microvascular Decompression in Hemifacial Spasm: ~90% Cure Rate

Microvascular decompression via an inferior ventrolateral brainstem approach achieved long-term cure in ~90% of hemifacial spasm patients, with one-third experiencing delayed relief (n>300).

• Retrospective case series of more than 300 procedures.
• Delayed cure occurred in one-third of patients.
• Single-surgeon experience limits generalizability.
