Facial Nerve Decompression

Facial Nerve Decompression

The Facial Nerve Decompression is usually perfomed on patients suffering from permanent facial palsy which makes their faced brood down. Facial nerve decompression is caused by pressure on peripheral nerve which results in nerve impulse block and compression of facial nerve into the bony canal of temporal bone. The procedure is carried out to give a more symmetrical appearance to a patient’s face. This surgery might also help in reducing the symptom of the paralysis as the compression is released from the nerve.

What causes Facial Nerve Decompression?

  • Otitis Media (ear infection)
  • Tumor
  • Bell’s Palsy
  • Birth Injury
  • Herpes Zoster Oticus
  • Skull Fracture
  • Facial Injury
  • Parotid Swelling
  • Melkersson-Rosenthal Syndrome

Who carries out the surgery?

ENT surgeon carries out the Facial Nerve Decompression surgery as it is performed through the mastoid bone which is part of the ear. The surgeon removes the pieces of the mastoid bone to release the pressure from the facial nerve, giving it space to decompress.

What are the difficulties a patient may face?

Like any other surgery, the facial nerve decompression also has few dangers which a patient may face like hear loss, facial nerve injury, headache or meningitis.


In order to decompress a facial nerve a surgery would be conducted after examining a patient thoroughly. During the procedure, an incision will be made through a drill parallel to the compressed nerve. The doctors, then, will remove the bone around the compressed nerve with diamond burrs. This will result in relaxation of stress on the facial nerve. The final layer of the compressed bone will also be removed with the use of a hook or fisch nerve dissectors.
