Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objective: Quantify the benefits of myofunctional therapy associated to botulinum toxin injection in patients with long standing facial unilateral palsy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type ACTIVE_COMPARATOR

Botulinum Toxin Type A

Intervention Type DRUG

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

Intervention Type PROCEDURE

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.

myofunctional therapy

Intervention Type PROCEDURE

It also included isotonic maneuvers to increase muscle tonus and isokinetic maneuvers to increase force on the paralyzed side.
