Hemifacial Spasm, Blepharospasm
Hemifacial spasm (HFS) is the involuntary movement of the mimic muscles on one side of the face, periodically and intermittently, with sudden onset and short duration (from a few seconds to a few minutes). First of all, it settles unilaterally around the eyes, over time, it spreads to the facial muscles on the same side.
Blepharospasm (BS) is the involuntary spasm-induced closure of the eyelids on one or both sides.
In 1973, Alan B. Scott was the first to use BTX-A for the treatment of strabismus. Since 1979, the FDA (American Food and Drug Administration) has approved BTX-A for the treatment of strabismus; It is widely used for various therapeutic purposes. Clinical studies have been conducted on blepharospasm or hemifacial spasm, and in 1989 the World Health Organization approved its application in these diseases as well.
Today, botulinum toxin type A applications are an accepted treatment for many forms of movement disorders such as hemifacial spasm and blepharospasm.
Our experience is that local botulinum toxin therapy is a superior treatment, as it is effective, safe and long-lasting, and increases the quality of life in such patients.
