Arms	Assigned Interventions
Active Comparator: A: myofunctional prior to botulinum All the facial paralysis patients received treatment with botulinum toxin type A to the non-paralyzed side, according to the Institution Protocol. To the participants of Group A, botulinum toxin was applied after myofunctional therapy.	Drug: Botulinum Toxin Type A All the patients received a one-time treatment with botulinum toxin type A to the non-paralyzed side, according to the Institution Protocol,the total dose used per patient ranged from 15-69U, mean 37.9±5.4U. Other Name: BOTOX (Allergan) Procedure: myofunctional therapy All the patients were submitted to individual myofunctional therapy with the speech therapist, once a week, by four weeks.The myofunctional therapy began with isometric maneuvers for muscular elongation on the non paralyzed side, and on the paralyzed side when microsurgical reconstruction was present. It also included isotonic maneuvers to increase muscle tonus and isokinetic maneuvers to increase force on the paralyzed side.
Active Comparator: B: myofunctional after botulinum All the facial paralysis patients received treatment with botulinum toxin type A to the non-paralyzed side, according to the Institution Protocol. To the participants of Group B, botulinum toxin was applied before myofunctional therapy.	Drug: Botulinum Toxin Type A All the patients received a one-time treatment with botulinum toxin type A to the non-paralyzed side, according to the Institution Protocol,the total dose used per patient ranged from 15-69U, mean 37.9±5.4U.

Detailed Description:

Twenty-five patients with long standing facial palsy were studied; all had been previously treated for facial reanimation. Patients were randomly divided in two groups; Group A did the myofunctional therapy sessions with the speech therapist before the botulinum toxin injection, while the participants of Group B did the myofunctional therapy after it.
