Introduction And Objectives:
Therapeutic indication of peripheral facial paralysis depends on the degree of nerve injury. Severe facial palsy (electroneuronographic study less than or equal to 10%) leads to healing with sequelae. The sequelae of facial paralysis are contractures, hemifacial spasm and synkinesis.Our purpose was to demonstrate that these patients could benefit from rehabilitation treatment.
Methods:
We present a study of 48 patients with severe peripheral facial paralysis. They were treated from the beginning of reinnervation with botulinum toxin and facial exercises according to the Wisconsin School.
Results:
The subjective efficacy of rehabilitation is high.
Conclusions:
Rehabilitation treatment can inform patients about their chances of recovery, give them control over and quality of facial expression and help to achieve greater facial symmetry. These factors provide better functionality and quality of life.
