Toxina botulínica en la distonía muscular de la ATM

Abstract

This investigation evaluated the effectiveness of the botulinum toxin type A in patients with temporomandibular joint dysfunction and oromandibular closing dystonia. Twenty persons were included between 29 and 61 years old, (90%) women, (10%) men. The trigger points were infiltrated, the pre-infiltration pain was measured with the analogous visual scale of the pain (AVS) and also weekly during 3 months. The mean value in the AVS of the initial pain was 8.15 points and for post-infiltration, the mean value was 3.7 points, with improvement of the pain of 45.3%. A new treatment with the botulinum toxin type A is proposed.
