Abstract
-
Thirty-nine patients with blepharospasm were treated with botulinum A toxin. Twenty-six patients had essential blepharospasm, and thirteen had hemifacial spasm. A total of 113 injections were given, and average follow-up was 14.6 months. The mean preinjection spasm intensity was 2.9+, and the mean post-injection spasm intensity was 0.7+. The mean interval between injections was 4.4 months. The treatment was effective, although transient, in all patients with essential blepharospasm and hemifacial spasm. The toxin had a prolonged effect on the patients who had previously undergone muscle stripping proced ure. The side effects were mild, transient, and local.
