Contralateral botulinum injections improve drinking ability and facial symmetry in patients with facial paralysis.

PURPOSE: To report two patients who experienced improved drinking ability as well as facial appearance with contralateral injection of botulinum toxin. DESIGN: Retrospective case reports. METHODS: Two patients were treated with botulinum toxin contralateral to the VIIth nerve palsy to improve drinking ability as well as facial asymmetry. RESULTS: Botulinum toxin injections improved facial asymmetry as well as drinking ability in two patients with facial nerve palsies. CONCLUSIONS: Contralateral botulinum toxin injections improved drinking ability in two patients with facial nerve palsy.
