Facial Nerve Decompression

Facial Nerve Decompression Patients suffering from permanent facial palsy opt for Facial Nerve Decompression. The pressure on the peripheral nerve causes facial nerve decompression which results in nerve impulse block and compression of the facial nerve into the bony canal of the temporal bone. The procedure is conducted 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?

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


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.

Who conducts the surgery?

The Facial Nerve Decompression surgery is conducted by an ENT Surgeon 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.

Are there any risks involved?

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