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.
3D image for Hemifacial Spasm
Facial nerve (blue) runs inside of Auditory nerve (yellow).
An artery has a contact with the facial nerve REZ.
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.
