Fifteen patients with hemifacial spasm were treated with botulinum A toxin
injections. All patients experienced relief from spasm, with the effect
lasting an average of 12.2 weeks. Complications were tearing in four
patients, inability to close the involved eye in three patients, corneal
exposure in one patient, and ectropion in one patient. All complications
were transient and deemed minor by the patients.
