Another form of treatment is the form of botox injections. Botulinum toxin, or Botox is a toxin produced by the C. botulinum bacteria that causes musle paralysis by blocking electrical messages that direct the muscle to move.
A very fine needle is used is used to deliver 1 to 3 injections into the facial muscles. Botox usually works within 3 days and lasts for 3 months.
Another part of treatment is surgery. Medications and injection may be inadequate at times to control spasms and cause side effects.
A procedure known as a microvascular decompression can relieve the nerve compression. In this procedure, a neurosurgeon makes a hole in the bone (craniotomy) at the back of the head to expose the facial nerve at the brainstem A teflon sponge is then placed between the offending blood vessel and the facial nerve.
About 90% of patients return to their regular lifestyle after two months. Like all surgeries, their are risks. More frequent side effects can include decreased hearing and facial weakness.
In general, the results of surgery include the following: 85% experience immedite relief from spasms, 9% report diminished spasm, 2% report delay in facial spasm in the month following surgery and 7% experience a recurrence of spasms after surgery.
There is no known way to prevent hemifacial spasms.
