Hemifacial Spasm

We provide surgical treatment for hemifacial spasm.
Hemifacial spasm is caused by vascular compression on the most sensitive part of the facial nerve (REZ).
Microvascular decompression moves the artery away from the REZ, which leads to stabilize facial spasm.
Same as trigeminal neuralgia, 3D preoperative imaging is very useful for hemifacial spasm as well.
It is crucial that a surgeon should understand the anatomical relation between the facial nerve and adjacent cranial nerves and arteries.

¡Microvascular Decompression for Hemifacial Spasm
  • Precise preoperative imaging.
  • Key hole surgery through a small skin incision.
  • Transposition technique applied rather than interposition, which contributes to lower recurrence rate.
  • No suture on the skin, which enables to early discharge from the hospital.
  • Hospital stay is normally less than 4 days.

Operative view
Tortuous artery contacts facial nerve on its REZ.
Operative view of Hemifacial Spasm Larger artery (Vertebral artery) can be a cause of hemifacial spasm
Tortuous artery runs on the REZ Teflon felt is used for transposition of the artery.
¡Teflon mass removal: Re-do operation

This patient had prior MVD with interposition technique.
HFS persisted due to too much Teflon inserted between the nerve and the compressing artery (microvascular recompression).
After removal of the excess of Teflon felt and appropriate transposition of the artery with sling technique, her symptoms were cured immediately after surgery.
 


Too much Teflon is compressing the facial nerve.
 


Teflon was removed and the compressing artery is exposed.
 


The artery is now transposed with the sling technique.
The REZ of facial nerve is free from any kind of compression.
