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.
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.
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.
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.
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.
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.
