Is treatment available for long-term cases of Bell's palsy?
Botox® (Botulinum toxin) injections may be used to to help people with long-term Bell's palsy by: relaxing facial muscles of the affected side of the face if they become too tight; reducing unwanted movements of muscles on the affected side of the face because of abnormal nerve fiber regrowth (such as eye-mouth synkinesis); relaxing facial muscles on the unaffected side of the face if they become overactive and also to improve symmetry and appearance, and; helping to prevent eye watering when eating. The effect of these injections is temporary; they need to be repeated about every four months.
