Hemifacial Spasm is often described as a chronic disease that occurs unilaterally with periodic clonic or tonic contractions of the facial muscles. Carbamazepine, clonazepam, nerve block, myectomy, facial nerve neuroctomy, neurosurgical microvascular decompression and botulinum toxin application may be listed as the preferred methods and agents for treatment. Botulinum toxin application is preferred more than medical treatment because it has longer duration of effect, easier to apply and better side effect profile. Botulinum toxin causes paralysis in muscles. This effect is dose-dependent by inhibiting the release of acetylcholine from the terminal membrane. A rare side effect of botulinum toxin application is atrophy, which occurs in applied muscles. Although there is no definitive data on the mechanisms of atrophy development, it is known that this effect occurs with chronic applications. In addition, muscle fiber type, schwann and satellite cell count, mitochondrial mechanisms, and blood perfusion in the muscle were evaluated for the risk of developing atrophy. In this case, a patient who developed atrophy in the facial muscles after chronic botulinum toxin administration was discussed.
